I'd like to see this implemented, at least for greater/less than (-or equal
to).
a < b < c
a <= b <= c
Desugars to
a < b && b < c
a <= b && b <= c
As a workaround, consider that ES6 arrow functions are going to
make something like this readable:
function sortedBy(op,...args) {
for(var i=1; i<args.length; i++) {
if (!op( args[i-1], args[i])) return false;
}
return true;
}
console.log( sortedBy( (a,b)=>a<b, 2,3,4) ); // true
console.log( sortedBy( (a,b)=>a<b, 2,4,3) ); // false
console.log( sortedBy( (a,b)=>a<b, 2,2,3) ); // false
console.log( sortedBy( (a,b)=>a<=b, 2,2,3) ); // true
