Each function should have a ‘name‘ property. It can be anonymous, empty, the same as function name, or class name.
For example:
const foo = function(){} console.log(foo.name); //foo
function(){ .. }); // name:
(function*(){ .. }); // name:
window.foo = function(){ .. }; // name:
class Awesome {
constructor() { .. } // name: Awesome
funny() { .. } // name: funny
}
var c = class Awesome { .. }; // name: Awesome
var o = {
foo() { .. }, // name: foo
*bar() { .. }, // name: bar
baz: () => { .. }, // name: baz
bam: function(){ .. }, // name: bam
get qux() { .. }, // name: get qux
set fuz() { .. }, // name: set fuz
["b" + "iz"]:
function(){ .. }, // name: biz
[Symbol( "buz" )]:
function(){ .. } // name: [buz]
};
export default function() { .. } // name: default
var y = new Function(); // name: anonymous
var GeneratorFunction =
function*(){}.__proto__.constructor;
var z = new GeneratorFunction(); // name: anonymous
[Javascript] MetaProgramming: function name
