IN JS ONLY NEEDED SOLUTION Here, we have 1 followed by a space, operator followed by another space and 2. For the challenge, we are going to have only two numbers between 1 valid operator. The return value should be a number. eval() is not allowed. In case of division, whenever the second number equals "0" return -1 For example: "15 / 0" → -1 Examples arithmeticOperation arithmeticOperation ("12 + 12") → 24 ("12 - 12") <-24
