# Lua Loops
In many cases, we need to perform some regular, repetitive operations. Therefore, in a program, we need to execute certain statements repeatedly.
A set of statements that are executed repeatedly is called a loop body. Whether the repetition can continue is determined by the loop's termination condition.
A loop structure is a control structure that repeatedly executes a certain program segment under specific conditions. The program segment that is repeatedly executed is called the loop body.
A loop statement consists of two parts: the loop body and the loop termination condition.
The Lua language provides the following loop handling methods:
| Loop Type | Description |
| --- | --- |
| (#) | Repeats executing certain statements while the condition is true. The condition is checked before the statement is executed. |
| (#) | Repeats executing specified statements, with the number of repetitions controlled within the for statement. |
| [repeat...until](#) | Repeats executing the loop until the specified condition becomes true. |
| (#) | You can nest one or more loop statements within a loop (while do ... end; for ... do ... end; repeat ... until;). |

## Loop Control Statements
Loop control statements are used to control the program's flow to implement various program structures.
Lua supports the following loop control statements:
| Control Statement | Description |
| --- | --- |
| (#) | Exits the current loop or statement and begins executing the immediately following statement in the script. |
| (#) | Transfers the program's control point to a label. |

## Infinite Loop
If the condition in the loop body is always true, the loop statement will execute forever. Here is an example using a while loop:
## Example
while(true)
do
print("The loop will execute forever")
end
