Asynchronous JavaScript Programming
This document provides an overview of asynchronous JavaScript. It discusses how JavaScript uses a single thread and event queue. It introduces asynchronous functions and loading scripts asynchronously. It covers the requestIdleCallback function for background tasks. The document also provides an in-depth overview of promises in JavaScript for asynchronous code, including the promise lifecycle, then and catch methods, and creating promises using the Promise constructor.
ES6 presentation
The document discusses key features of ECMAScript 6 (ES6), including:
- Default parameters, template literals, multi-line strings, spread operator, and enhanced object literals which add concise syntaxes.
- Arrow functions which provide a shorter syntax for writing anonymous functions.
- Block-scoped constructs like let and const that add block scoping to variables and constants.
- Classes which provide a cleaner way to define constructor functions and objects.
- Hoisting differences between function declarations and class declarations.
- Using ES6 today by compiling it to ES5 using a tool like Babel.
Reactive Java Microservices with Spring Boot and JHipster - Spring I/O 2022
Microservice architectures are all the rage in JavaLand. They allow teams to develop services independently and deploy autonomously.
Why microservices?
IF
you are developing a large/complex application
AND
you need to deliver it rapidly, frequently, and reliably over a long period of time
THEN
the Microservice Architecture is often a good choice.
Reactive architectures are becoming increasingly popular for organizations that need to do more, with less hardware. Reactive programming allows you to build systems that are resilient to high load.
In this session, I'll show you how to use JHipster to create a reactive microservices architecture with Spring Boot, Spring Cloud, Keycloak, and run it all in Docker. You will leave with the know-how to create your own resilient apps!

AngularJS Architecture
AngularJS uses a compile function to parse HTML into DOM elements and compile directives. The compile function sorts directives by priority and executes their compile and link functions to connect the scope to the DOM. It recursively compiles child elements. This allows directives to manipulate DOM elements and register behavior.
JavaScript Promises
A presentation of what are JavaScript Promises, what problems they solve and how to use them. Dissects some Bluebird features, the most complete Promise library available for NodeJS and browser.
Java Script ppt
JavaScript is a scripting language that allows dynamic interactivity on web pages. It was invented by Brendan Eich and can be used to create image galleries, layout changes, and button click responses. JavaScript code can be placed between <script> tags in HTML documents or in external .js files. Some key features include client-side execution in web browsers, dynamic rendering variations across browsers, and potential security issues if not implemented carefully. Common uses of JavaScript include manipulating DOM elements, handling events, and validating forms.
JavaScript for ABAP Programmers - 4/7 Scope
This document discusses JavaScript execution contexts and variable/property declarations in the global context. There are three execution contexts: the global context, function contexts, and eval contexts. The global context is created once for the entire runtime and is accessible via the window object in browsers. Variables are declared with var and belong to the variable object of their context, while properties without var automatically belong to the global/window object. This can make global variables appear similar to properties.
The New JavaScript: ES6
This year ECMA International will be ratifying the biggest update to the JavaScript language in its history. In this talk we'll look at key features already appearing in browsers as well as those coming in the near future. We'll also explore how you can begin leveraging the power of ES6 across all browsers today. If you haven't looked at JavaScript recently, you soon realize that a bigger, better world awaits.
Cypress for Testing
Cypress is an open source, front end testing tool built for modern web applications. It uses JavaScript to write automated end-to-end tests that run directly in the browser engine. Unlike Selenium which runs outside the browser, Cypress operates inside the browser to listen and modify behavior. Cypress makes testing simple through its intuitive API, fast speeds, and ability to work on any frontend framework. The document outlines Cypress' architecture, features, limitations, installation process, project structure, and how to write tests using constructs like describe, it, before, and assertions.
Lab #2: Introduction to Javascript
This document provides an introduction to JavaScript and its uses for web programming. It explains that JavaScript is a client-side scripting language that allows web pages to become interactive. Some key points covered include:
- JavaScript can change HTML content, styles, validate data, and make calculations.
- Functions are blocks of code that perform tasks when invoked by events or called in code.
- Events like clicks or keyboard presses trigger JavaScript code.
- The DOM (Document Object Model) represents an HTML document that JavaScript can access and modify.
- Forms and user input can be accessed and processed using the DOM.
- Programming flow can be controlled with conditional and loop statements.

El nuevo tipo de datos "símbolo" o "symbol"
Los “símbolos” son un nuevo tipo de dato primitivo.
Los símbolos son únicos e inmutables y son utilizados como identificadores para propiedades de objetos.

Nuevas características de los objetos en JavaScript ES6
1. Sintaxis corta para los objetos:
2. Soporte de nombres calculados en la definición de propiedades
3. Soporte de notación tipo método en la definición de propiedades, en forma regular y como función generadora.
4. Método assign() para copiar objetos
Nuevos Métodos en ES6
ES6, ECMAScript 6, ES2015, Javascript, Nuevos Métodos en ES6, Asignación de propiedad de objeto, método assign(), búsqueda de un elemento en un arreglo, find(), findindex(), Repetición de cadenas, repeat(), Búsqueda de cadenas, startsWith(), endsWith(), includes(), Comprobación de tipo de número, isNaN(), isFinite(), Infinity(), isSafeInteger(), Epsilon, trunc(), signo de un número, sign()
Objetos de propagación o ...spread
La sintaxis de Spread nos permite expandir la expresión para los siguientes casos:
Arreglos (arrays)
Llamadas a Funciones
Mejoras en las expresiones regulares
La bandera “y” mantiene la posición entre coincidencias mediante el parámetro lastIndex, por lo que se le llama “búsqueda pegajosa” o “bandera adhesiva”.
Valores por default en argumentos
En EcmaScript 6 podemos recibir valor por omisión o default en los parámetros de las funciones. Pueden ser definidos como variables primitivas, funciones, expresiones o arreglos.
Literales octales y binarias:
Hay ocasiones en que el contexto de nuestros datos requiere que trabajemos con cifras no decimales, por ejemplo en base 2 (binario) o base 8 (octal), ahora es sencillo crear este tipo de literales con los prefijos (0b) y (0o) respectivamente.
La programación orientada a objetos con JavaScript ES6
Ahora podemos hacer clases por medio de la sentencia “class”.
Podemos utilizar el método “ constructor()” para crear la función constructora.
Los lenguajes tradicionales basados en clases ofrecen la palabra reservada this para referencia la instancia actual de la clase.
En Javascript this se refiere al contexto de la llamada y como tal puede ser cambiado a algo más que un objeto

Las etiquetas estructurales en html5
Las nuevas etiquetas estructurales de HTML5 incluyen <section>, <article>, <aside>, <header>, <hgroup>, <footer>, y <nav> para organizar el contenido de una página. El documento explica el propósito de cada etiqueta y sugiere cómo usarlas, aunque su uso depende del criterio del desarrollador. Las etiquetas estructurales ayudan a los navegadores y buscadores a comprender mejor la estructura de una página.
Los metadatos de HTML5
El documento describe los metadatos básicos en HTML5, incluyendo la etiqueta <meta charset="utf-8"> para indicar el conjunto de caracteres de la página, la etiqueta <title> para el título de la página, y cómo guardar la página como un archivo HTML5 para verla en un navegador.
El doctype de HTML5
El documento explica las directivas <!DOCTYPE> para diferentes versiones de HTML y XHTML que especifican el tipo de documento y ayudan a los navegadores a renderizar el contenido de forma adecuada. La directiva <!DOCTYPE> para XHTML es más larga que para HTML4.01 e incluye referencias, mientras que para HTML5 simplemente es <!DOCTYPE HTML>.
Historia de HTML5
El HTML5 comenzó a desarrollarse en 2004 y ha ido evolucionando gradualmente desde entonces, con especificaciones clave en 2005, 2006, 2008 y 2012 que agregaron nuevas características como aplicaciones web, multimedia, gráficos y más funcionalidad, convirtiéndose en 2020 en un estándar ampliamente adoptado.

En el momento actual hay suficiente evidencia que
demuestra que el impacto social de los desórdenes por
deficiencia de yodo es muy grande y que su prevención resulta
en una mejor calidad de vida y de la productividad, así como
también de la capacidad de educación de los niños y adultos.
Prevención y tratamiento de los DDI
Los desórdenes por deficiencia de yodo pueden ser
exitosamente prevenidos mediante programas de suplementa-
ción de yodo. A través de la historia se han ensayado varios
medios para tal propósito, pero la estrategia más costo-efectiva

entre 1907 a 1921 probaron que la deficiencia
y la suplementación de yodo eran factores dominantes en la
etiología y el control del bocio endémico. El uso experimental
de la sal yodada para la prevención del bocio endémico se llevó
a cabo en Akron, Ohio, con resultados espectaculares y fue

son contrahechos, jibados, tartamudos, de ojos torcidos y con
unos deformes tumores en la garganta, que aquí llaman cotos y
otras semejantes deformidades en el cuerpo y sus corres-
pondientes en el ánimo”. Y es lógico aceptar como cierto este
hecho, dado que la deficiencia de yodo en la Cordillera de los
Andes es un fenómeno ambiental permanente desde sus
orígenes.
Luego de la Independencia hasta los años 1950s, la
persistencia del bocio y el cretinismo endémicos en la sierra y la
selva fue reportada por varios autores, cuyos importantes
