## Syntax - Exercise


Let's practice the function syntax:

<br>

**Task 1**

Create function called `fullName` using *function declaration* syntax.

The function should take 2 arguments, `firstName` and `lastName` and `return` a new string representing the full name.



```js
// Your code here

console.log( fullName('Bob', 'Smith') ); //  expected: Bob Smith
```



<br>



**Task 2**

Create the same  function as a function expression, but this time name it `fullNameExpr`.

```js
// Your code here

console.log( fullNameExpr('Sarah', 'O\'Connor') ); //  expected: Sarah O'Connor
```



<br>



**Task 3**

Create the same as arrow function, but this time name it `fullNameArrow`.

```js
// Your code here

console.log( fullNameArrow('Axel', 'Garcia') ); //  expected: Axel Garcia
```



<br>



**Bonus** -

Create the same function as concise arrow function.

```js
// Your code here

console.log( fullNameArrow('Esther', 'Bernal') ); //  expected: Esther bernal
```
