How to use map() method In Javascript
The map() function in JavaScript allows you to access an array of objects and change it into another array. The map() function calls a supplied function on each element of the original array, producing the results in a new array.
Syntax:
arrayName.map((item) => {
console.log(item);
});
Example: The code below demonstrates how we can use the forEach loop to access the elements of the array of objects.
Javascript
// Array of objects let objArr = [ { name: 'john' , age: 12, gender: 'male' }, { name: 'jane' , age: 15, gender: 'female' }, { name: 'julie' , age: 20, gender: 'trans' } ]; console.log( "Accessing the Array using the forEach loop:" ) objArr.map((item) => { console.log(item); }); |
Output
Accessing the Array using the forEach loop: { name: 'john', age: 12, gender: 'male' } { name: 'jane', age: 15, gender: 'female' } { name: 'julie', age: 20, gender: 'trans' }
