Function property after bind
الأهمية: 5
There’s a value in the property of a function. Will it change after bind
? Why, or why not?
function sayHi() {
alert( this.name );
}
sayHi.test = 5;
let bound = sayHi.bind({
name: "John"
});
alert( bound.test ); // what will be the output? why?
The answer: undefined
.
The result of bind
is another object. It does not have the test
property.
