You can see the syntax. The map() function loops through an array using a callback function (or the mapping function). Each element in the array is sent to the callback function, which returns a new element. The map() creates a new array using the returned elements.
Syntax
array.map(callback[, thisObject]);
Parameters
callback − It produces an element for the new array from an element of the current one.
thisObject − when executing the callback, this Object is used.
The map () executes as an alternative to our for loops. It reduces the length of your code and requires a little practice.
Benefits of using array map():
- You don't have to define any index. Since you operate with the array element, you don't have to define any index.
- No need to create a new array and push elements into it.
- Don't have to create any loop.
- We have to put in a return statement. Otherwise, we will get an array of undefined.
- You feel free to assign to a new variable because the map returns a finished array
- It does not access the function for empty elements.
- It does not change the original array.
