Loops in Go

For Loop

For loops in go works the same as any other programming language. To make a for loop that does 3 iterations,

for i:=0; i < 3; i++ {
    fmt.Println(i) 
}
// Outputs: 0,1,2

break keyword

break keyword is used to stop the for loop from iterating further.

for i:=0; i < 4; i++ {
    if i == 2 {
      break
    }
    fmt.Println(i)
}
// Outputs: 0,1

continue keyword

continue keyword is used to skip an iteration.

for i:=0; i < 3; i++ {
    if i == 1 {
      continue
    }
    fmt.Println(i)
}
// Outputs: 0,2

range keyword
