Jennifer is a lesbian. Her wife, now husband, who she’s proudly supportive of, is FtM, with 3 previous children that Jennifer adopted. Jennifer has never had penetrative sex with a man.
artificial insemination; beard marriage, loves her husband platonically. I am a JS dev.
Lesbian, in marriage with another lesbian and adopted 3 kids. Still virgin.
Java devs are prima mental gymnasticists, always able to make anything make sense.
JS !== Java
Try Javascript some day!
- We have truthy and falsy! Empty string or null? Yeah, that’s false!
- Of course we can parse a string to number, but if it’s not a number it’s NaN!
- null >= 0 is true!
- Assign a variable with =, test type equality with == and test actual equality with ===. You will NEVER use the wrong amount of = anywhere, trust me!
- Our default sort converts everything to string, then sorts by UTF-16 code. So yes, [1, 10, 3] is sorted and you are going to live with it.
- True + true = 2. You know I’m right.

I’m not sure whether this is satire or not.
Simple. Malformed data from.a bad actor. Always sanity check your shit.
If you have that much difficulty with JavaScript then it’s likely you’ll suffer with any language.
Except strict equality, that’s a JavaScript only problem. Imagine thinking "0" should be falsy in comparison due to string literal evaluation, but truthy with logical not applied based on non-empty string. Thus !"0"=="0" is true. They couldn’t just throw away == and start over nooooo let’s add === . Utter madness
Browser compatibility. Design flaws can’t easily be fixed like how other languages can just switch to a new major version and introduce breaking changes. ES must keep backwards compatibility so has had to do more additive changes than replacing behavior altogether so that older web pages pages don’t break.
Strict vs loose equality has gotten me so many times, but I can sort of see why they did it. The problem you mention with integers 0 & 1 is a major annoyance though. Like it is fairly common to check whether a variable is populated by using if (variable) {} - if the variable happens to be an integer, and that integer happens to be 0, loose quality will reflect that as false.
But on the other side, there have been plenty of occasions where I’m expecting a boolean to come from somewhere and instead the data is passed as a text string. “true” == true but “true” !== true
Lua does intrinsic evaluation of strings that i’d argue is not nearly as crazy. I get the value of it since half of interpreted languages it just churning through strings. But I also don’t recommend any large codebase ever use JS’s == or string coercion because it can go against expectations. This graph argues in JS’s favor but comparison is a little more crazy https://algassert.com/visualization/2014/03/27/Better-JS-Equality-Table.html
