# Function in an object in JavaScript

Using symbols, functions can be added to objects and these functions will not participate in the looping. Let's try. Let's have an object:

`let obj = {a: 1, b: 2, c: 3};`

Let's create a symbol:

`let sym = Symbol();`

Write a function to an object with a key in the form of our symbol:

`obj[sym] = function() { console.log('!!!'); };`

When iterating over the object, our function will not be iterated:

`for (let key in obj) { console.log(obj[key]); // 1, 2, 3 }`

We get our function by passing our symbol (the same variable) as a key:

`let func = obj[sym]; func();`

We can shorten the code:

`obj[sym]();`

Add a function to the object that will display the current time. Call this function.
