Where's the >== operator? Because they also have the exact same problem.

The recommended ESLint rules catch most of the bad stuff, and these days this is all you need in your ESLint config to enable them:

import {defineConfig} from 'eslint/config';
import js from '@eslint/js' 

export default defineConfig([
  js.configs.recommended,
]; 

There's one use case where == is still commonly used: == null matches both null and undefined. Lint rules that block == usually allows the null case as an exception.

As someone trying to learn Javascript, it just makes me mad that at this garbage heap of a language is so widely used.

IIRC modern linter rulesets generally just outright error if you do anything remotely like this.

== has never, ever caused me a single issue. Parsing all server input with type-safe schemas makes sure that where I expect a string, I get a string; where I expect a number, I get a number. Bad data must result in an error before it reaches logic.

When I had to use JS I wrote JS 1.2 because why not. Fun how I had strings of numbers instead of actual numbers in some for loops, yet it all sort of functioned until something didn't. I then decided to add Number() to random values just in case.

No

As someone who last touched any C++ books when C++11 was very new and has only written like 20-30 lines of non-tutorial C++ since then, what are some significant changes to the language that I should be aware of if I wanted to give it a try now?
