I need a couple sentences about Creating and testing JavaScript.

Expert Solution

`Hey,

Note: Brother in case of any queries, just comment in box I would be very happy to assist all your queries

JavaScript is true scripting and with new resources like Node.js and TypeScript it’s becoming much more powerful.

Simple JS unit testing will take a function, monitor output and return its behavior. Smashing Magazine has a great example which tests a calendar date output function based on a specific type of input.

Every unit test is made to check against an individual unit in JavaScript, which typically breaks down to a function or library. The goal is to check every aspect of the function to make sure it all works properly for all cases.

Please keep in mind that the JavaScript test suite is run on a wide variety of wildly varying hardware plaforms, from phones all the way up to servers. Even tests that check for polynomial time complexity will start to fail in a few years when they have sped up enough to run faster than the granularity of the OS scheduler or when run on platforms with higher latencies than your development workstation. These tests will also show up as infrequent oranges on our heavily loaded test machines, lowering the value of our test suite for everyone. Just don't do it, it's never worth it.

Kindly revert for any queries

Thanks.
