combine two arrays javascript
let arr1 = [0, 1, 2];
let arr2 = [3, 5, 7];
let primes = arr1.concat(arr2);
// > [0, 1, 2, 3, 5, 7]combine two arrays javascript
let arr1 = [0, 1, 2];
let arr2 = [3, 5, 7];
let primes = arr1.concat(arr2);
// > [0, 1, 2, 3, 5, 7]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);Concatenate two arrays
Array -- Concatenate two arrays
Write a return method that can concatenate two arrays
Solution:
public static int[] concatTwoArrays(int[] arr1 , int[] arr2) {
int[] result = new int[arr1.length + arr2.length];
int i = 0;
for(int each: arr1) {
result[i] = each;
i++;
}
for(int each: arr2) {
result[i] =each;
i++;
}
return result;
}merge arrays in javascript
var array1 = ["Vijendra", "Singh"];
var array2 = ["Singh", "Shakya"];
console.log(array1.concat(array2));combine 2 arrays javascript
//ES6 using the spread operator
const itemsA = [ 'Lightsaber', 'Mockingjay pin', 'Box of chocolates' ];
const itemsB = [ 'Ghost trap', 'The One Ring', 'DeLorean' ]
const allItems = [ ...itemsA, ...itemsB ];merge array within an array
var arrays = [
["$6"],
["$12"],
["$25"],
["$25"],
["$18"],
["$22"],
["$10"]
];
var merged = [].concat.apply([], arrays);
console.log(merged);
