What is JavaScript? – For Web Development
Fri, 07 May 2021
JavaScript is a Web-based programming language. JavaScript is a web browser programming language intended to make web pages feel alive. This can update and modify both HTML and CSS, and data can be measured, manipulated, and validated.
A Quick Definition of JavaScript
JavaScript is a scripting language used to build and manage dynamic content on the internet, anything that moves, refreshes, or otherwise changes on your computer without forcing you to manually reload a web page.
We use JavaScript for:
Interact with user
Use functions and calculate useful values for the user to see, use
Make changes on UI – Add/Change/Remove elements within DOM
Make requests to the servers
Store and read values from cookies
Store data locally for faster work with a web page and many more
Features of JavaScript:
Animated graphics
Photo slideshows
Autocomplete text suggestions
Interactive forms
The Power of-HTML, CSS, and JavaScript
When most people learn to code, the good old HTML and CSS start. They switch on to JavaScript from there. That makes sense that together, the three elements form the backbone of web creation.
HTML-is your page layout headers, body text, any photos you want to add
CSS-controls how the page looks, it’s what you’re going to use to modify fonts, background colors, etc.
JavaScript-is the third magic item. Once you’ve built your framework (HTML) and visual feel (CSS), JavaScript can dynamize your site or project.
Why is JavaScript Used For?
There’s a shortlist of key items for which JavaScript is used.
Adding website interactivity — yup, if you want a website to be more than a static text page, you’ll need to do some Java Scripting
Designing Mobile Applications — JavaScript isn’t only for websites. It’s used to build those apps you’ve got on your phone and tablet as well as.
Designing web browser-based games — JavaScript also helped to make Back end.
Web development happens —JavaScript is mainly used at the front end of things, but it’s a flexible scripting language that can also be used on back end infrastructure.
What kind of language is JavaScript?
JavaScript is a prototype-based language
A class is an instruction on how to create an object, and that class is an instance of an object. A software language, like JavaScript, does not make the distinction. It has objected.
We can define properties for any object; we can do so at runtime or when we build them. This makes JavaScript ideal for server communication, as servers can modify data structures and the code will still function.
