Mutable variable is accessible from closure. How can I fix this?

I liked the paragraph Closures Inside Loops from Javascript Garden

It explains three ways of doing it.

The wrong way of using a closure inside a loop

for(var i = 0; i < 10; i++) {
    setTimeout(function() {
        console.log(i);  
    }, 1000);
}

Solution 1 with anonymous wrapper

for(var i = 0; i < 10; i++) {
    (function(e) {
        setTimeout(function() {
            console.log(e);  
        }, 1000);
    })(i);
}

Solution 2 – returning a function from a closure

for(var i = 0; i < 10; i++) {
    setTimeout((function(e) {
        return function() {
            console.log(e);
        }
    })(i), 1000)
}

Solution 3, my favorite, where I think I finally understood bind – yaay! bind FTW!

for(var i = 0; i < 10; i++) {
    setTimeout(console.log.bind(console, i), 1000);
}

I highly recommend Javascript garden – it showed me this and many more Javascript quirks (and made me like JS even more).

p.s. if your brain didn’t melt you haven’t had enough Javascript that day.
