[JS Practice] Array Appender

Title :

Array Appender


You are the greatest chef on earth. No one boils eggs like you! Your restaurant is always full of guests, who love your boiled eggs. But when there is a greater order of boiled eggs, you need some time, because you have only one pot for your job. How much time do you need?

Your Task

Write a function called appendArrays that appends the items from array 2 onto array 1, returning the newly formed array.

For example if your 2 arrays were:

var array1 = [a,b,c]
var array2 = [1,2,3]

After using your appendArrays function, the result should be[a,b,c,1,2,3]

Your function should also be able to handle nested arrays.

For example, combining array [['x','x'],'B'] with array['c','D'] should return [['x','x'],'B','c','D'].

Your solution should account for a situation for either the first or second inputs aren’t actually arrays.

// basic test
Test.assertSimilar(appendArrays(['this'],['that']), ['this','that'])

// second input is not an array
Test.assertSimilar(appendArrays([1,2], [1]), [1,2,1])

// first input is not an array
Test.assertSimilar(appendArrays([2], [1,1,1]), [2,1,1,1])

My solution :

function combineArray(arr1, arr2) {
  return arr1.concat(arr2);
