| console.log(1) | |
| // this line will "continue" the previous one so | |
| // it gets a semicolon to stop it from doing that | |
| // JS would otherwise consider it a function call, | |
| // ie `console.log("hello")(function() { ... }) | |
| ;(function() { | |
| console.log(2) | |
| })() | |
| // this one, too, it would otherwise be... what I\'d | |
| // call "bracket access", like how you access array | |
| // elements | |
| ;[3, 4, 5].forEach(i => console.log(i)) | |
| // this one is well behaved, it doesn\'t need a semicolon | |
| Number.prototype.times = function times(fn) { | |
| for(i=0; i < this; ++i) fn(i) | |
| } | |
| // the minus here could be a binary operator, so: semicolon | |
| ;3..times(i => console.log(i+6)) |
