Recap - Simple Calculator

Part of the Fundamentals section of Coddy's JavaScript journey — lesson 25 of 77.

Challenge

Beginner

You are given a code that gets as input two numbers n1 and n2 and a character op (given).

The possible values for op are '+', '-', '/' and '*'

Your task is to set the variable result based on the conditions:

if op is '+', set result with n1 + n2.
if op is '-', set result with n1 - n2.
if op is '/', set result with n1 / n2.
if op is '*', set result with n1 * n2.

Try it yourself

let n1 = parseInt(inp[0]) // Don't change this line
let n2 = parseInt(inp[1]) // Don't change this line
let op = inp[2] // Don't change this line
let result = 0



// Don't change the line below
console.log(`result = ${result}`)
