You don't need to be a language guru to know which operation will be performed first, you can (and should) check an operator precedence and associativity table such as MDN's <https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Operator_Precedence> . Knowing operator precedence and associativity is very important when reading code written by others, and many projects use the "no unnecessary parens" linting rule.
