Introduction to Modern JavaScript

Let's look at what makes JavaScript unique, what we can accomplish with it, and what other technologies work well with it.

What is JavaScript, and how does it work?
JavaScript was invented to "bring web pages to life."

Scripts are the name for the programs written in this language. They can be written directly in the HTML of a web page and run when the page loaded.

Scripts are provided in plain text format and executed as such. They don't require any extra setup or compilation to execute.

In this regard, JavaScript differs significantly from the Java programming language.

Why is it called JavaScript?
When JavaScript was created, it initially had another name: “LiveScript”. But Java was very popular at that time, so it was decided that positioning a new language as a “younger brother” of Java would help.

But as it evolved, JavaScript became a fully independent language with its own specification called ECMAScript, and now it has no relation to Java at all.

What distinguishes JavaScript from other scripting languages?
JavaScript is great for at least three reasons:

HTML/CSS integration is complete.
Simple tasks are completed in a straightforward manner.
All major browsers support it, and it's turned on by default.
The only browser technology that combines all three features is JavaScript.

That is what distinguishes JavaScript from other scripting languages. As a result, it is the most widely used tool for designing browser interfaces.

JavaScript, on the other hand, can be used to develop servers, mobile applications, and other applications.

JavaScript was designed to be a browser-only language, but it is currently utilized in a variety of other settings.
JavaScript now holds the distinction of being the most extensively used browser language, completely integrated with HTML/CSS.
Many languages are "translated" into JavaScript and provide specific functionality. After mastering JavaScript, it is recommended that you take a look at them, at least briefly.
