When it does so without the new keyword, // it’s a factory function. // create function function createMemberShp(firstName, lastName) { // remember use return here return { firstName: firstName, lastName: lastName, fullName: function () { console.log(`Hello ${this.firstName} ${this.lastName}`); }, }; } // dont forget field argument cz function use param const lutfy = createMemberShp('mugiwara no', 'luttfy'); lutfy.fullName(); // Hello mugiwara no luttfy const zoro = createMemberShp('Roronoa', 'Zorro'); zoro.fullName(); //Hello Roronoa Zorro /***** Cara ini lebih efektif dibandingkan harus membuat object seperti membuat object lutfy terlebih dahulu, dilanjut dengan object zoro terlebih dahulu jika harus membuat 3000 lebih tidak efektif juga jadi factory funciton adalah solusinya.. ******/ |
