## Builder, Factory and Repository pattern with Javascript

> Util content: [dofacory.com/javascript/design-patterns](https://www.dofactory.com/javascript/design-patterns)

### Builder pattern

* Useful for creating custom behaviors, using methods with descriptive names.

* It's a lot like a production line, where each employee performs a single function.

##### Example

```js

myBuilderFunction

  .stepOne()

  .stepTwo()

  .stepThree()

  .stepFour()

  .finish()

```

### Factory pattern

* Useful for concentrating instance creation in one place.

* Gives the possibility to crate some logic when creating an instance.

##### Example

```js

function createOjbInstance(optionalParam) {

  const param = optionalParam || "I am a default param"

  return new MyClass(param)

}

const objOne = createObjInstance()

const objTwo = createObjInstance()

const objThree = createOjbInstance("I am an optional parameter")

const objFour = createOjbInstance()

```

### Repository pattern

* Useful for abstracting data persistence.

* Methods have descriptive names (find, findById, findByName, create, save, delete, remove etc).

##### Example

```js

const myRepository = new MyRepositoryClass()

myRepository.save({ id: "123abc", fieldOne: "one", fieldTwo: "two" })

myRepository.save({ id: "456dfg", fieldOne: "three", fieldTwo: "four" })

const allRepositoryData = myRepository.find()

// [{ id: "123abc", fieldOne: "one", fieldTwo: "two" }, { id: "456dfg", fieldOne: "three", fieldTwo: "four" }]

```

## What the hell is Tereré?
