Arguments’ names in JavaScript
This is more of a reminder to myself, but it can be useful to anyone wishing to add a little more reflection to JS :
Function.prototype.args = function () {
return this.toString()
.match(/\(([^)]*)\)/)[1]
.replace(/\s*/g, ").split(',');
}
function foo (bar, baz, quux) {
return 42;
}
foo.args();
// = [bar, baz, quux]
return this.toString()
.match(/\(([^)]*)\)/)[1]
.replace(/\s*/g, ").split(',');
}
function foo (bar, baz, quux) {
return 42;
}
foo.args();
// = [bar, baz, quux]
