Basic JavaScript: Return a Value from a Function with Return

We can pass values into a function with arguments. You can use a return statement to send a value back out of a function.

Example

function plusThree(num) {

  return num + 3;

}

var answer = plusThree(5); // 8

plusThree takes an argument for num and returns a value equal to num + 3.

Create a function timesFive that accepts one argument, multiplies it by 5, and returns the new value. See the last line in the editor for an example of how you can test your timesFive function.

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).

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