to the Q

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 it hard to learn JavaScript?

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.

Is it worth it to 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. We even have a Neural Network course, here on Scrimba, that uses Javascript. Yes, it is definitely worth learning.
