Use the assignment operator `=`

to assign a value to a variable:

```
const a = 2
let b = 2
var c = 2
```

This operator has several shortcuts for all the arithmetic operators which let you assign to the first operand the result of the operations with the second operand.

They are:

`+=`

: addition assignment`-=`

: subtraction assignment`*=`

: multiplication assignment`/=`

: division assignment`%=`

: remainder assignment`**=`

: exponentiation assignment

Examples:

```
let a = 0
a += 5 //a === 5
a -= 2 //a === 3
a *= 2 //a === 6
a /= 2 //a === 3
a %= 2 //a === 1
```

To be clear, the above operations are executed one after another, so

`a`

at the end is 1, not 0
