go run .

go build 

Section 1: Variables

Variables in Go

• Normal variable

  var a int = 10
• Shorthand

  a := 10

Section 2: Loops

For Loop Variants

• Normal For Loop

  for i := 0; i < 10; i++ {
      // do something
  }
• While Loop Style - For Loop

  i := 0
  for  i < 10 {
      // do something
      i++
  }
• Infinite Loop

  for  {
      // do something
  }
  // OR 
  for true  {
      // do something
  }

Section 3: Multiple Return

Return Multiple values from a Method

• Code example

  func go() (int error) {
      return 0, nil
  }
  
  func main() {
      i, err := foo()
      if err !=nil {
          panic(err)
      } 
  	println(i)
  }

Section 4: Defer keyword

Section 5: new vs make

Make is only used with a slice, map and channel(chan)
Make initializes the underlying datastuctures for above mentioned DS
```
    func main() {
        type TypeStruct struct {
            Name string
        }

        t := new(TestStruct) // type *TestStruct - Create an Object with Zero values of the variables
        var v TestStruct // type TestStruct
    }
```

Section 8: concurrency/waitGroups(making the main thread wait)/mutex(remove race condition)/channels(passing data to routines) ?

Misc:

Returning a function or array of functions from a function New vs Make

Functional style programming is possible ?
