// 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"]

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([

[40, 50, 60]
])
arr2_2d = npy.array([
[11, 22, 33],
