Keywords¶

fn - begins a function declaration in any of these shapes:
1. Pure function without specified return type i.e. having the default void return type.
```
fn name()
fn name(arg int, arg2 string, ...)
```
2. Pure function with specified return type.
```
fn name() int
fn name(arg int, arg2 string, ...) int
```
3. Struct method without and with argument and result types.
```
fn (m MyStruct) name() int
fn (m MyStruct) name(arg int, arg2 string, ...) int
```
For more examples and explanation check functions and methods in V documentation.
import - imports a module so a program can access it and its public symbols such as constants, structs or functions
mut - makes a variable mutable (editable)
in - checks whether array or map on the right side contains a value on the left side (value in array, see in keyword for more)
break - breaks an iteration of a for loop
const - declares a module-level variable that will never change (see const keyword for more)
return - returns a value from a function
exit - exits a program when encountered, allows user to specify the exit code for operating system
continue - immediately skips to the next iteration of a loop
break - stops the loop from any further iteration
panic - exits a program and marks the program as unsuccessfully stopped with an exit code.
