<pre>* SUMMARY
console.assert should do far less work when the assertion is true.
* TEST
<script>
(function() {
function bench(name, f, arg) {
var warmup = f();
var start = Date.now();
var result = f();
var end = Date.now();
console.log(name, (end-start)+"ms");
}
bench("console.assert...", function() {
for (var i = 0; i < 1e6; ++i)
console.assert(true, "message");
});
})();
</script>
* RESULTS
• Safari - console.assert... – "119ms"
• Chrome - console.assert... 22ms
• Firefox - console.assert... 44ms
We do a lot of work in the case where the assert doesn't fire. After a quick fix:
• Safari - console.assert... – "9ms"</pre>
