After experimenting with THREE.js for a while, I came across something peculiar:
When using Firefox and opening the developer console to type camera.lookAt (assuming your camera is named camera), it displays
function THREE.Camera.prototype.lookAt</<()I'm intrigued by the presence of </< and its origins, as it seems to be invalid in JavaScript function names. This is the first time I've encountered this and I've attempted to replicate it without success so far.
FireFox has specific rules for assigning names to anonymous functions, which helps in displaying them in the console and call stack. The function lookAt is actually anonymous.
To see this in action, open the code snippet below in FireFox, then access the console and type nonymous.
index.html:
<script>
var nonymous = function() {
return function() {
}
}();
</script>
Console Result:
> nonymous
< function nonymous</<()
