# Loops
## For loop
Braces are required.
```thp
let numbers = [0, 1, 2, 3]
for number in numbers
{
print(number)
}
for #(index, number) in numbers.entries()
{
print("{index} => {number}")
}
```
```thp
let dict = Obj {
apple: 10,
banana: 7,
cherries: 3,
}
for #(key, value) in dict
{
print("{key} => {value}")
}
```
```thp
for value in collection
{
if condition
{
break
}
}
```
## While loop
```thp
let colors = ["red", "green", "blue"]
let mut index = 0
while index < colors.size()
{
print("{colors[index]}")
index += 1
}
```
## Infinite loop
Basically Rust*'s loop.
```thp
loop
{
print("looping")
if condition
{
break
}
}
```
