In this analysis, functions that reference an "alias" to this (e.g. var
self = this) within an inner scope are counted:
(function() {
var self = this;
(function() { console.log(self); });
});
This results in 1 BTF candidate (the inner function).
In my analysis, I mention that this methodology will tend to undercount the
BTF candidates, because functions with explicitly bound "this" (through
Function.prototype.bind or other means) will tend to get marked as
"methods":
element.onclick = function() {
console.log(this);
}.bind(this);
The analyzer reports 0 BTF candidates, even though we clearly should have
1. Since the tool undercounts, we can say that the reported numbers offer
a lower bound on BTF candidacy. The fact that BFT candidacy may be higher
doesn't alter the analysis.
