brandonvanha / getAllPropertyNames.js
Last active August 29, 2015 14:07
Iterates over all properties (not just enumerable ones).
function getAllPropertyNames(obj) {
var result = [];
while (obj) {
// Add the own property names of `obj` to `result`
Array.prototype.push.apply(result, Object.getOwnPropertyNames(obj));
obj = Object.getPrototypeOf(obj);
}
return result;
}

Efficient Codes
• Apply the array method map() to a string:
> [].map.call('abc', function (x) { return x.toUpperCase() })
[ 'A', 'B', 'C' ]
Using map() generically is more efficient than using split(''), which creates an intermediate array:
> 'abc'.split('').map(function (x) { return x.toUpperCase() })
[ 'A', 'B', 'C' ]
Apply a string method to nonstrings. toUpperCase() converts the receiver to a string and uppercases the result:
> String.prototype.toUpperCase.call(true)

Cheat Sheet: Working with Objects
This section is a quick reference with pointers to more thorough explanations.
• Object literals (see “Object Literals” on page 198):
var jane = {
name: 'Jane',
'not an identifier': 123,
describe: function () { // method
return 'Person named '+this.name;
},

Be aware of sharing clearing arrays
Clearing shared arrays
You need to be aware of the fact that setting an array’s length to zero affects everybody
who shares the array:
> var a1 = [1, 2, 3];
> var a2 = a1;
> a1.length = 0;
> a1
[]
> a2
