In javascript, you can rewrite a function, like so:
function foo() {
setTimeout(function() {
alert('sup stallion');
foo = function() { //rewrite foo to nolonger wait 4 seconds to alert.
alert('sup stallion');
}
}, 4000);
}
Obviously this is a contrived example, but is there anything conceptually wrong with this approach (other than a race condition).
Self modifying code can be confusing, and hard to debug, so it’s generally avoided.
Other than that there is no problem, and no race condition either.
