That doesn't work. Your browser is just going to freeze up if you do this:

while (1) {}

You can however use a setInterval.

snakeclass.prototype.start = function() {
    var interval;
    var doo = function () {
        if(this.collision()){
            console.log("game over");
            clearInterval(interval);
        }
        this.movesnake();
    }.bind(this); // bind this so it can be accessed again inside the function
    doo();
    timeout = setInterval(doo, 300);
};
