Amazing list of resources for Javascript Interview

Are you preparing for a Javascript interview?. Then this list may help you to crack the interview.

In the past 4 years I have interviewed for around 20 companies and created a list of things that these companies often ask.

I agree, you agree that Javascript interview is a bit different than the other software engineer interviews.

So I have separated the preparation in three different parts.

1. Data Structures and Algorithms (To test the problem solving skills).
2. Web development and Computer science stuffs (To test the computer science skills).
3. Javascript specific questions (To test the grip on the language).

• Understanding javascript programming language in order to use it.

1. ESNext (Javascript with latest stuffs).

• Data Structures in javascript

1. Array
2. Object.
3. Strings.

This is the effort of last two years when I had decided to solve problems and post them on my blog. There is a long way ahead and I am planning to make it bigger by adding more useful resources.

Please do check them and if you think this will be helpful in any way then share with your friends.

Also from the coming Monday (02/03/2020). I will be sharing how to create different types of components in React and many more cool stuffs.

you can follow me on Twitter @learnersbucket for regular updates.
