## What is go?
6+
7+
>Go is a general-purpose language designed with systems programming in mind. It was initially developed at Google in the year 2007 by Robert Griesemer, Rob Pike, and Ken Thompson. It is strongly and statically typed, provides inbuilt support for garbage collection, and supports concurrent programming.

# Creational Design pattern
2+
3+
> Creational design pattern deals with object creation. In general, we used to create object using new keyword which is a pretty hard approach. It gives zero flexibility, if we need to decide object instantiation according to situations. Creational design pattern came to solve this issue.
4+
5+
According to the ```(GOF)``` There are six creational design patterns.

# Builder Pattern
2+
```xml
3+
The Builder pattern helps us construct complex objects without directly instantiating their
4+
struct, or writing the logic they require. Imagine an object that could have dozens of fields
5+
that are more complex structs themselves. Now imagine that you have many objects with these
6+
characteristics, and you could have more. We don't want to write the logic to create all these
7+
objects in the package that just needs to use the objects.
8+
```
9+
10+
### Objectives
11+
- Abstract complex creations so that object creation is separated from the object
12+
user
13+
- Create an object step by step by filling its fields and creating the embedded
14+
objects
15+
16+
### About the example
17+
we are going to implement a car builder
18+
19+
### Acceptance criteria
20+
- To be able to build a object step by step with needed property
