## Loops

Go has only one looping construct, the **for** loop.

The basic **for** loop has three components separated by semicolons:

  - the init statement: executed before the first iteration

  - the condition expression: evaluated before every iteration

  - the post statement: executed at the end of every iteration

The init statement will often be a short variable declaration, and the variables declared there are visible only in the scope of the for statement.

The loop will stop iterating once the boolean condition evaluates to false.

**Note**: Unlike other languages like *C*, *Java*, or *JavaScript* there are no parentheses surrounding the three components of the for statement and the braces { } are always required

## Examples

```go
package main

import "fmt"

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