Javascript Shrunk Part 1
3 Ways of building the same javascript counter
The two “slowest”
var a = function() {
if (!arguments.callee.i) arguments.callee.i = 0;
return ++arguments.callee.i;
}
var b = function() {
return arguments.callee.i ? ++arguments.callee.i: arguments.callee.i = 0;
}
The two “fastest”
var c = function() {
return this.i ? ++this.i: this.i = 0;
}
var d = function() {
return this.i = ++this.i || 0;
}
Example Output:
a() // => 1
a() // => 2
a() // => 3
...
b() // => 1
b() // => 2
b() // => 3
etc...
