Adding elements using "push" in JavaScript
Using the special method push,
you can add elements to the end of an array.
Let's see how it's done. Let's say we have
the following array:
let arr = [];
Add three elements to its end:
arr.push('a');
arr.push('b');
arr.push('c');
Let's see what happened:
console.log(arr); // shows ['a', 'b', 'c']
Fill an array with numbers 1,
2 and 3.
Let such an array be given:
let arr = [1, 2, 3];
Add the elements 4 and
5 to its end.
