ES6 I tutorial codes

## Replace var
```
//declare a variable which can be reassigned to another value
let name = 'my name';

//defines a variable whose value is not reassignable
const PI = 3.14;
```

## No more stress with complex strings

```
let student = {name : 'Harry', age : '18'};

//See how representing it is easier with ``

let description = `I'm a student my name is ${student.name}
                   I'm ${student.age} years old.`;

console.log(description);
```

## Destructuring

```
//Extracting values from an array. 
const axis = [10, 25, -34];

const [x, y, z] = axis;

console.log(x, y, z);
//Extracting values from an object.
const man = {
  name: 'Peter',
  age: '30',
  height: 185
};

const {name, age, height} = man;

console.log(name, age, height);
```

## Object Literal

```
  name = 'Peter';
  age = '30';
  height = 185;

const man = {
  name,
  age,
  height
};
///Creates a man object and automatically set its name, age and height properties

console.log(man);

//Prints : {name: "Peter", age: "30", height: 185}

```

## The Cool For Of Loop

``` 
const numbers = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9];
 for(let number of numbers)
{
  console.log(number);
}
```

## Spread it

```
const weapons = ["gun", "sword", "spirit bomb"];
console.log(...weapons);
```

## Get The Rest of it

```
const weapons = ["gun", "sword","catana", "spirit bomb", "shuriken"];
const [weapon1, weapon2, weapon3, ...otherWeapons] = weapons;
console.log(weapon1, weapon2, weapon3, otherWeapons);
function sum(...nums) {
  let total = 0;  
  for(const num of nums) {
    total += num;
  }
  return total;
}
```
