JavaScript

What is JavaScript?

JavaScript is a dynamic computer programming language. It is lightweight and most commonly used as a part of web pages, whose implementations allow client-side script to interact with the user and make dynamic pages. It is an interpreted programming language with object-oriented capabilities.

Here are some of the features of JavaScript:

• JavaScript gives HTML designers a programming tool - HTML authors are normally not programmers, but JavaScript is a scripting language with a very simple syntax! Almost anyone can put small "snippets" of code into their HTML pages.
• JavaScript can put dynamic text into an HTML page - A JavaScript statement like this: document.write("<h1>" + name + " </h1>") can write a variable text into an HTML page.
• JavaScript can react to events - A JavaScript can be set to execute when something happens, like when a page has finished loading or when a user clicks on an HTML element.
• JavaScript can read and write HTML elements - A JavaScript can read and change the content of an HTML element. • JavaScript can be used to validate data - A JavaScript can be used to validate form data before it is submitted to a server. This saves the server from extra processing.
• JavaScript can be used to detect the visitor's browser - A JavaScript can be used to detect the visitor's browser, and - depending on the browser - load another page specifically designed for that browser.
• JavaScript can be used to create cookies - A JavaScript can be used to store and retrieve information on the visitor's computer.

Uses of JavaScript are:

1.Front-End Development: When used with HTML and CSS, Java Script creates the most dynamic and interactive pages. JavaScript allows web pages to respond to user activity and dynamically update themselves, and all without requiring a page reload to change its appearance. It gives the site additional functionality that isn’t otherwise achievable with HTML and CSS alone. 

2. Back-End Development: Node js has contributed both to back end and increasing the performance of the front end. Node is a popular choice for building back end largely due to the fact that it shares the same base language, JavaScript, as many front-ends. This allows developers and teams to contribute, share and reuse code across the stack and manage full-stack projects with a single package manager.

 3. Building Web Apps: Angular, React Native can be used to build hybrid apps using HTML, CSS, and JavaScript. JavaScript is extensively used by web developers to create various web applications and to add interactive features to them. Most of the internet browsers support JavaScript, which allows dynamic content to get displayed beautifully on web pages. 

4. Mobile App Development: JavaScript comes with frameworks tailored to make progressive Web Apps. Neither Apple nor Android phones will run a native app written in JavaScript .They also let you maintain one code base for several different devices. Main languages used to develop all mobile apps are HTML, CSS, and JavaScript. 

5. Machine Learning: Tensor Flow.js and MI.js are popular machine learning JavaScript libraries.as are the dynamics of ML engineering. And it’s become common practice for developers to write machine learning functions using common web-scripting languages. These days, it’s possible to build and train an algorithm using any general-purpose programming and that includes JavaScript.

 

6. Deep Learning: Libraries- brain.js, ConvNetJS, deeplearn.JS are there to train neural networks in the browser. JavaScript, one of the core programming languages and it has been used by the researchers to implement and develop deep learning techniques.
