Javascript Calculator help

JavaScript

Hi All,

I’ve been trying to complete the Javascript calculator code, but I keep failing on test 13::

If 2 or more operators are entered consecutively, the operation performed should be the last operator entered (excluding the negative (-) sign.

What is the best way to solve this

Here is my codepen:

Thanks!!!

Hi @mirajhaq

The code will fail as it only allows one operator at a time.

You need to refactor so that if more than one operator is input, the first operator is ignored and second operator is accepted.

Unless the second operator is the minus sign, then accept both operators.

So:
5 / + 5 becomes five plus five = ten
5 + - 5 becomes 5 plus negative five = 0
5 * - 5 becomes five times negative five = negative twenty five

Also two decimal points in a row will fail the tests.

Happy coding
