// 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

#// 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)
concat multiple arrays in javascript
const concatArrays = (...arrays) => {
let concatenatedArray = [];
for(let i=0; i<arrays.length; i++){

}
else
return false;
}

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'];
const array2 = ['d', 'e', 'f'];
const array3 = array1.concat(array2);
console.log(array3);
// expected output: Array ["a", "b", "c", "d", "e", "f"]
