没有变量的“true ===”有什么作用？

Question

The following code is not mine. Created by Microsoft Azure for window.appInsights. This code works in Edge & IE, but fails in Chrome (throws "SyntaxError: expected expression, got '&&'" in the console). Firefox complains about it, but works anyway.

Can someone explain to me what this is doing (attempting to do)? I've not seen something like this before.

if (true === && "" !== "") {

UPDATE Thank you all for your answers. I thought it was poorly written code, but wanted to be sure it didn't contain a coding shorthand I wasn't aware of. Your answers cleared that up for me !

Answer 1

It probably is a mistake. It shouldn't work. === is a binary operator and therefore expects 2 operands not 1. && is not an expression neither a valid identifier.

Read it in english. if true is strictly equal to or empty string is strictly not equal to empty string

i wonder what "" !== "" is trying to do since it will always evaluate to false lol
