Is there a way to provide named parameters in a function call in JavaScript?
...sole.log('a is ' + a, ' | b is ' + b, ' | c is ' + c);
});
foo(1, 2, 3); // a is 1 | b is 2 | c is 3
foo(1, {b:2, c:3}); // a is 1 | b is 2 | c is 3
foo(1, {c:3}); // a is 1 | b is undefined | c is 3
foo({a: 1, c:3}); // a is 1 | b is undefined | c is 3
