var args = Array.prototype.slice.call(arguments, 1);
var i = 0;

Thanks for sharing, smartly done! I es6-ified it into:

function sprintf(format, ...args) {
    let i = 0;
    return format.replace(/%s/g, () => args[i++]);
}

I love it!

const sprintf = ( format, ...args ) => ( i = 0, format.replace( /%s/g, () => args[i++] ) );

My version in arrow function.
