In programming, it's often useful to assign the value of one variable to another variable. This allows you to create multiple references to the same value, which can be helpful in a variety of contexts.

To assign the value of one variable to another, you simply use the assignment operator `=` followed by the variable you want to assign the value to. For example, let's say you have a variable `x` and you want to create a variable `y` with the value of the `x` variable:


``` javascript
let x = 5;
let y = x;
```

Now, both x and y have the value of `5`.

If you change the value of `x` later, y will still hold the original value of `5`, because it's a separate variable.

``` javascript
let x = 5;
let y = x;

x = 10;

console.log(x) // output: 10
console.log(y) // output: 5
```

---

Now answer the question:

What is the value of `y` in the following code?

``` javascript
let x = 5;
let y = x;

x = 10;

console.log(y)
```
