push() Array Method
Use push() to add one or more elements to the end of an array. It will also return the length of the new array.
Here is a quick example:
let fruits =['apple','banana'];fruits.push('kiwi','mango');console.log(fruits);// Output: ['apple', 'banana', 'kiwi', 'mango']Alternatively, instead of just pushing new elements into the array, you could assign the push to a variable like so and retrieve it's new length at the same time as pushing the new elements into the array:
let fruits =['apple','banana'];let fruits_length = fruits.push('kiwi','mango');console.log(fruits_length);// Output: 4console.log(fruits);// Output: ['apple', 'banana', 'kiwi', 'mango']Syntax and Parameters
