One of the most popular methods of iterating through datasets in JavaScript is the `.map()` method. `.map()` creates an array from calling a specific function on each item in the parent array. `.map()` is a non-mutating method that creates a new array instead of changing the original. In this tutorial, we’ll look at four noteworthy uses of `.map()` in JavaScript: calling a function of array elements, converting strings to arrays, rendering lists in libraries, and reformatting array objects.

JavaScript est un langage basé sur des prototypes, et chaque objet en JavaScript possède une propriété interne cachée appelée [[Prototype]] qui peut être utilisée pour étendre les propriétés et les méthodes des objets. Vous pouvez en savoir plus sur les prototypes dans notre…

In ECMAScript 2015, generators were introduced to the JavaScript language. A generator is a process that can be paused and resumed and can yield multiple values. They can maintain state, providing an efficient way to make iterators, and are capable of dealing with infinite data streams. In this article, we’ll cover how to create generator functions, how to iterate over Generator objects, the difference between yield and return inside a generator, and other aspects of working with generators.
