For Loops

• There is only for loop in go.
• continue and break statements have the same effect as in any other language.

  for i := 0; i<10; i++ {
      fmt.Println(i)
  }
  

• Third statement is flexible in go

  // ; after i < 10 is important
  for i := 0; i<10; {
      fmt.Println(i)
      i++
  }
  

• While loop using for

  i := 0
  for i < 10 {
      fmt.Println(i)
      i++
  }
  

• Infinite loop

  for {
      // statements
  }
  for i := 0; true; i++ {
      // statements
  }
  

• Handling multiple variables in a for loop

  for i, j := 0, 100; i < 10; i, j = i+1, j+1 {
      fmt.Printf("i = %v, j = %v\n", i, j)
  }
  

• Iterating over an array

  for index, value := range someArray {
      // statements
  }
  // if you don't want index you can use _ instead of index
