# Imperative vs Declarative

#### Imperative:

It is a code that says the machine, what to do and how to do.

```javascript
Ex:
for (let i = 0; i < 1000; i++) {
    console.log(i);
}
```

#### Declarative:

It is a code that says the machine, what to do and what should happen. It doesn't tell how to do. `Ex: Humans`

```javascript
Ex:
[1, 2, 3].forEach(item => console.log(item));
```

Functional programming is mostly be a declarative, we don't say how to do.
