browser support. All these neat new features arriving in JS that I don't know if I can use or not
libraries that use .map(index, item) vs .map(item, index) (The latter is the better BTW)

funky auto-casting
double trouble 0.1+0.2 != 0.3

=== and !==
"Optional" semi-colons
Frameworks that multiply like Tribbles
