JavaScript JoelThe best code,
without tests,
not to be trusted.
function alwaysLeft(left) {
return function(right) {
return left
}
}
Test coverage,
gives confidence,
still can be busted.
alwaysLeft('L')('R') === 'L'
Code abused,
ways unimagined,
leaving you disgusted.
function I(x) {
return x
}
alwaysLeft(I)('L')('R') === 'R'
