Increment and decrement operators are used to increase or decrease the value of a variable by 1.

The increment operator `++` adds 1 to the variable, and the decrement operator `--` subtracts 1 from the variable.

Here's an example:

```javascript
let count = 0;

count++; // increases count to 1
console.log(count); // outputs 1

count--; // decreases count back to 0
console.log(count); // outputs 0
```

These operators can also be used before the variable (pre-increment/decrement) or after the variable (post-increment/decrement), which affects when the value is changed.

Pre-increment/decrement changes the value before any other operations are performed, while post-increment/decrement changes the value after all other operations are performed.

Here's an example:

```javascript
let num1 = 0;
let num2 = 0;

num1 = ++num2; // pre-increment: num1 is now 1, num2 is 1
console.log(num1); // outputs 1
console.log(num2); // outputs 1
```

In this example, the value of `num2` is incremented before the assignment is performed. So, `num1` is assigned the value of `num2`, which is `1`.

```javascript
let num1 = 0;
let num2 = 0;

num1 = num2++; // post-increment: num1 is now 0, num2 is 1
console.log(num1); // outputs 0
console.log(num2); // outputs 1
```

In this example, the value of `num2` is incremented after the assignment is performed. So, `num1` is assigned the value of `num2`, which is `0`.

In the exercises below, you'll have a variable called `x` assigned to `5`. Select all the options that will allow to make the `y` variable equal to `6`.

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