In this tutorial, you will learn about the JavaScript Array flatMap() method with the help of examples. The flatMap() method first maps each element of an array using a mapping function, then flattens it into a new array.
map(params, 'name'); }; This handles the original parse issue and a few more function types (e.g. arrow functions). Here's an idea of what it can and can't handle as is: // I usually use mocha as the test runner and chai as the assertion library describe('Extracts argument ...
