Why does javascript throw this error - REALLY! Why do we have to have work arounds for native partial applications in javascript. It's bad from a developer point of view that we have to increase boiler plate for functions that should be callable but isn't! Could this be solved by the fat arrow, where the scope is defined already in the function …

illegal-invocation.js

function apply(f) {
  return function(x) {
    return f(x);
  };
}

apply(console.log)(2);

// Using fat arrow.
function apply(f) {
  return (x) => f(x);
}
