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);js merge 2 lists
var array1 = ["Vijendra", "Singh"];
var array2 = ["Singh", "Shakya"];
console.log(array1.concat(array2));
// output: ["Vijendra", "Singh", "Singh", "Shakya"]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;
}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 ];how to concatenate two arrays
