FAQ

How long it will take to learn JavaScript?

The answer to this question is highly individual. Depending on how much time you can dedicate to studying, the basic concepts in this course can be covered and practised in about 3 hours. To become reasonably proficient at Javascript might take another 6 months.

Is JavaScript easy to learn?

In many ways, it's one of the easiest languages to learn. You can write some code in Developer Tools in your browser and see the results straight away. There are a lot of materials on Javascript and the barrier to entry is quite low. Some of the more advanced Javascript concepts might be tricky even for experienced professionals. But that shouldn't deter you in the slightest. In summary, we believe it's easy to learn, but can be hard at times, but that's ok.

Why should I learn JavaScript?

Javascript is ubiquitous and it is hugely in demand. Javascript can be used on the customer-facing web apps, web servers on the backend, productivity-improving scripts and IoT devices. We even have a Neural Network course, here on Scrimba, that uses Javascript. Yes, it is definitely worth learning.

Are JavaScript developers in demand?

Yes, very. Javascript is the most popular language in the world according to multiple developer surveys conducted by Github, Stack Overflow and many others. Considering how wide-spread the language is the demand only grows.

What's the difference between ECMAScript and JavaScript?

ECMA means European Computer Manufacturer's Association. ECMAScript is a programming language standard and JavaScript is its implementation. ECMAScript specifies the core features that a language should provide and how those features should be implemented. JavaScript was originally created at Netscape, and they wanted to standardize the language. So, they submitted the language to the European Computer Manufacturer's Association (ECMA) for standardization. But there were trademark issues with the name JavaScript, and the standard became called ECMAScript, which is the name it holds today as well.
