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.

Try Javascript today!

I'm not sure whether this is satire or not.

It's not. The default sorter does that, because that way it can sort pretty much anything without breaking at runtime. You can overwrite it easily, though. For the example above you could simply do it like this:

[3, 1, 10].sort((a, b) => a - b)

Returns: [1, 3, 10]

who the fuck decided that not breaking at runtime was more important than making sense?

this js example of [1, 3, 10].sort() vs [1, 3, 10].sort((a, b) => a - b) will be my go to example of why good defaults are important
