Currying in Javascript | Understanding JS Interview Question

Understanding Curry function in Javascript with a JS interview question example.

Hello everyone! My name is Ashutosh Bhardwaj. And in this video, we'll take a deep look at Currying in Javascript.

The functional programming paradigm has been gaining traction in the Javascript community for quite some time. It's hard to pinpoint when it all started, but I believe with the introduction of features like arrow functions, map, filter, reduce, etc., in ES6 (2015), we're seeing a lot more functional programming code in Javascript.
Therefore, it would be fair to say one might expect functional programming questions in a Javascript interview. For instance, let's take a look at the following problem statement:

Write a function that will provide the same output regardless of whether the arguments are passed all at once or one at a time(partially).
For example:
add3(1, 2, 3) // 6
add3(1)(2, 3) // 6
add3(1)(2)(3) // 6

No worries, in this video, we will learn how to implement such a function using functional programming concepts.
