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"]

javascript concat two arrays

//ES6
const array3 = [...array1, ...array2];

concat array javascript

const letters = ['a', 'b', 'c'];
const numbers = [1, 2, 3];

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

javascript how to merge arrays

const arrFirst = ['string1', 'string2'];
const arrSecond = ['string3','string4'];

const newArr = [...arrFirst, ...arrSecond];

console.log(newArr);

concatenation array

#// required library
import numpy as npy

#// define 3 (1D) numpy arrays
arr1 = npy.array([10, 20, 30])
arr2 = npy.array([40, 50, 60])
arr3 = npy.array([70, 80, 90])

arrCon = npy.concatenate([arr1, arr2, arr3])
print(arrCon)

#// concatenation can also happen with 2D arrays
arr1_2d = npy.array([
  [10, 20, 30],
  [40, 50, 60]
])
arr2_2d = npy.array([
  [11, 22, 33],
  [44, 55, 66]
])

arr_2dCon = npy.concatenate([arr1_2d, arr2_2d])
print(arr_2dCon)

let arr2 = ['3', '4'];

let combarr = [].concat(arr1); //define new variable, empty array then concatenating arr1 to it
combarr = combarr.concat(arr2); //combarr = itself, then concatenating arr2 to the end
console.log(combarr); //Expected output: ['1','2','3','4']

js array concat

const array1 = ['a', 'b', 'c'];
