What is JavaScript?

모든 웹 브라우저에는 인터프리터(Interpreter)가 내장되어 있어서 자바스크립트를 실행할 수 있어요.

JavaScript , an object-based scripting programming language
You can do programming in various fields.

JavaScript is an object-based scripting programming language. All web browsers have a built-in interpreter that can execute JavaScript. This means that any device equipped with a web browser can run programs written in JavaScript.


JavaScript, why should I learn it?

Various development fields that can be done with JavaScript

With the advent of Node.js, JavaScript is no longer a language tied to web browsers. Its applications are expanding beyond web applications to desktop applications, mobile apps, kiosks, games, and even microcontrollers like Arduino.

JavaScript is Everywhere .

Just mastering the JavaScript language is expanding the possibilities. However, this also means that JavaScript requires advanced coding beyond the traditional HTML DOM manipulation in web browsers.

So, learn JavaScript properly
You have to be able to use it properly .


Learn JavaScript properly from the basics.

This course covers the fundamentals of JavaScript. But what exactly are the fundamentals ?
It is often mistaken that the basics of programming languages are learning basic grammar .

In Korea, a baby is considered one year old when born, and the first floor of a building is considered the first floor. However, things are different in Europe. Age is 0, and floors in a building are counted from the 0th floor. And in every programming language you're learning, array indices start at 0. In Korea, 0 is considered nonexistent, but in Europe, 0 is the starting point and foundation of everything.

We desperately need this zero. If you want to become a good developer, you absolutely cannot overlook this zero. In this course, you will learn the fundamentals of JavaScript.

The base is 0,
It is the starting point and the base .

This course will provide you with a solid foundation for understanding the JavaScript language. You'll be confidently equipped to tackle the countless applications you'll create in JavaScript in the future.

    Thank you for explaining each and every one of them, including how to use it and what it is actually used for. When I study by Googling, I often have more complicated experiences because of the scattered information, but since it is all gathered together like this, it was easy to organize. I will wait for the next intermediate course. Thank you so much.
