Infinity and NaN a identifiers referencing properties on the global object —
they’re not literals (nor is undefined).
These are all valid (but you shouldn’t do it):
function f(undefined, NaN, Infinity) {
// dooooooommmmmm
}
function f() {
var undefined = null /* fix that silly null vs. undefined shenanigans */, NaN =
Math.sqrt(2) /* make sure nan is not rational */, Infinity = 10000000 /* this
should be big enough */
}
