var Terminal = function() {
  this.walk = function() {
    alert('hello');
  }
  this.go = 'walk';
  this.move = 'walk';
}

var term = new Terminal();
var fn = 'walk';
if (term.hasOwnProperty(fn)) {
  term.{fn};
}

How can I run the method term.walk() using the string ‘walk’?

Answer 1

There are a couple of ways. The simplest is

term[fn]();

Or alternatively

var funcObj = term[fn];
funcObj.apply(term);
