ReferenceError: Invalid left-hand side in assignment?

Question

my code for a rock paper scissors game (called toss) is as follows: var toss = function (one,two) { if(one = "rock" && two = "rock") { console.log("Tie! Try again!"); } // more similar conditions with `else if` }; When I enter in the parameters toss("rock","rock") I get this error code: >"ReferenceError: Invalid left-hand side in assignment" How to fix it? What this error means and what other cases when this error can happen?

Answer 1

JavaScript uses the "==" and "===" operators for equality. "=" is for assignment.

You can fix your error by using either "==" or "===". They are different. Please do a little research before deciding which fits your use case.
