[JS Practice] Array Appender

Title :

Array Appender

Description:

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);
}
