If you’re new to JavaScript or just want to understand some of its most powerful array methods, you’ve come to the right place! Today, I’ll explain map (), filter (), and reduce () with easy examples and show you when to use each.
This part of the JavaScripttutorial introduces maps. It covers how to create maps, accessing and deleting the unique key-value pairs, cloning and merging maps and the conversion from a map to a regular object or array and vice versa.
JavaScriptMaps are a powerful way to store key-value pairs, offering better performance and flexibility compared to traditional objects. In this tutorial, we’ll explore everything you need to know about Maps, from creating them to using their methods effectively.
Description map() creates a new array from calling a function for every array element. map() does not execute the function for empty elements. map() does not change the original array.
A JavaScriptMap holds key-value pairs and similar to Hash Map or Dictionary in other languages. Preserves the original insertion order. Supports any type, including objects and primitives, as keys or values. This feature allows for efficient data retrieval and manipulation.
This JavaScriptmapstutorial will give you an introduction to the concept of Maps in JavaScript. In this video, JavaScriptMaps are explained with suitable examples.
