Basic Algorithm Scripting: Slice and Splice

Basic Algorithm Scripting: Slice and Splice

You are given two arrays and an index.

Use the array methods slice and splice to copy each element of the first array into the second array, in order.

Begin inserting elements at index n of the second array.

Return the resulting array. The input arrays should remain the same after the function runs.

Remember to use Read-Search-Ask if you get stuck. Write your own code.

Seek & Destroy

Return the lowest index at which a value (second argument) should be inserted into an array (first argument) once it has been sorted. The returned value should be a number.

For example, getIndexToIns([1,2,3,4], 1.5)should return 1 because it is greater than 1(index 0), but less than 2 (index 1).

Likewise, getIndexToIns([20,3,5], 19)should return 2 because once the array has been sorted it will look like [3,5,20] and 19 is less than 20 (index 2) and greater than 5 (index 1).
