let arr2 = [3, 5, 7];
let primes = arr1.concat(arr2);
// > [0, 1, 2, 3, 5, 7]
javascript combine array of arrays
/* Flatten (merge) an array of arrays with reduce & concat */
let myArrays = [[1, 2, 3], [4, 5], [6]];
myArrays.reduce((initial, current) => initial.concat(current), []);
// → [1, 2, 3, 4, 5, 6]

let neutral = ["brown", "gray"];
let colors = warm.concat(cool).concat(neutral);
// → ["red", "orange", "blue", "purple", "brown", "gray"]
javascript merge array
// ES5 version use Array.concat:
let array1 = ["a", "b"]
let array2 = ["1", "2"]
let combinedArray = array1.concat(array2);
// combinedArray == ["a", "b", "1", "2"]
// ES6 version use destructuring:
let array1 = ["a", "b"]
let array2 = ["1", "2"]
let combinedArray = [...array1, ...array2]
// combinedArray == ["a", "b", "1", "2"]
concatenate multiple arrays javascript
const array1 = ['a', 'b', 'c'];
const array2 = ['d', 'e', 'f'];
const array3 = [...array1, ...array2];
console.log(array3);
// expected output: Array ["a", "b", "c", "d", "e", "f"]
