minus-square@[email protected]linkfedilink77•edit-21 year agoJS !== 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!

minus-square@[email protected]linkfedilink58•edit-21 year agoIt’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]

minus-square@[email protected]linkfedilink1•1 year agowho uses utf 16? people either use utf 8 (for files) or utf 32 (for string class O(1) random access)
minus-square@[email protected]linkfedilink1•1 year agoTrue + true = 2. I’ve heard memes about Javascript, but jeez. It’s really that bad?
