Hello Aspirant,

JavaScript is a high-level programming language of the web. There are many courses available online to learn this programming language. However, the time which you will require to complete the full course of javascript will vary according to your efficiency and the time you are ready to devote daily for your studies. On an average 1 month is a good time to complete the course. You can do it in even less time depending on hardwork you put in.

Good Luck
