Let's declare several variables:

```
let a = 1;
let b = 2;
let c = 3;
```

We can simplify the code above if we
write `let`

one time and listing
then the required variables with their
values after it, in such a way:

`let a = 1, b = 2, c = 3;`

You can first declare all variables, and then assign values to them:

```
let a, b, c; // declare all 3 variables
// Assigning values to variables:
a = 1;
b = 2;
c = 3;
```

Try all the described ways of declaring variables by yourself.
