V (programming language)
V, also known as vlang, is a compiled programming language created to be easier for using, reading, maintaining, and making safer programs.[3][4] It was created by Alexander Medvednikov in 2019.[5]

Some technical details
changeV is also general-purpose, which means that it can be used for different purposes, to include creating different kinds of applications that can be cross-platform.[5] V applications can be created to run on many different operating systems. The language also has various rules and features for greater program safety.[5][4]
Users don't have to care about managing memory themselves, unless they want to, because V gives different options. Users can use a garbage-collector (GC), which is 1 of 4 other choices.[6][7][8] Advanced users can choose to turn the GC off and manage memory themselves, using the other options from V.[5][8]
V works well with C. Functions in C can be called for use in V.[4] It can translate C code into V.[4] Code in V can also be compiled to human readable C, JavaScript, and other languages.[5][7]
Examples
changeHere is a hello world program in V.
println("Hello world!")
Here is an example of using a variable:
- Define by using
:=
and a value. - Variables that don't have
mut
, have values that can't be changed. - Variables that have
mut
before them can change values using=
.
a := 1 // value can not be changed
mut b := 2 // value can be changed
b = 3
Here is an example of using `if`, `else if` and `else` conditionals in V.
// Define entry point.
fn main() {
a := 10
b := 20
if a < b {
println("${a} < ${b}")
} else if a > b {
println("${a} > ${b}")
} else {
println("${a} == ${b}")
}
// Output: 10 < 20
}
Here are examples of how to use the for loop in V.
- In V, all types of loops use the same `for` keyword.
- This helps to make it easier to learn and separate them from other kinds of code.
// Define entry point.
fn main() {
// Here is a condition `for` loop (also known as a `while` loop).
mut count := 0
for count < 5 {
// some code
count++
println(count) // Prints numbers from 1 up to 5.
}
// Here is a range `for` loop.
for i in 1..10 {
println("Number: ${i}") // Prints numbers from 1 up to 9.
}
// Here is a map `for` loop.
m := {
"one": 1
"two": 2
}
for key, value in m {
println("${key} -> ${value}")
// Output: one -> 1
// two -> 2
}
// Here is a bare `for` loop.
mut num := 0
for {
num += 2
if num >= 10 {
break
}
}
println(num) // Prints "10".
// Here is a C style `for` loop.
for i := 0; i < 8; i += 2 {
// Don't print 4
if i == 4 {
continue
}
println(i) // Prints the numbers "0", "2", and "6".
}
}
