code-style: Is inline initialization of JS objects ok?
- by michael
I often find myself using inline initialization (see example below), especially in a switch statement when I don't know which case loop will hit. I find it easier to read than if statements.
But is this good practice or will it incur side-effects or a performance hit?
for (var i in array) {
var o = o ? o : {}; // init object if it doesn't exist
o[array[i]] = 1; // add key-values
}
Is there a good website to go to get coding style tips?
