Example 1: merge array in js
//for ES5
var array1 = ["Rahul", "Sachin"];
var array2 = ["Sehwag", "Kohli"];
var output = array1.concat(array2);
console.log(output);
//for ES6, we use spread operators to concat arrays
var array1 = ["Dravid", "Tendulkar"];
var array2 = ["Virendra", "Virat"];
var output = [...array1, ...array2];
console.log(output);
Example 2: concat array javascript
const letters = ['a', 'b', 'c'];

const newArray = letters.concat(numbers);
// newArrat is ['a', 'b', 'c', 1, 2, 3]
