i think you code look wrong in this part const obj = { name: "John Doe", myFunc() { printNmae: () => { console.log(this.name); } }, }; obj.printName() // '' you can't access the printNmae , for accessing the printNmae you have to return it. just do const obj={ name:"John Doe", myFunc(){ return { printNmae:()=>{console.log(this.name)} } } } obj.myFunc().printNmae();
