repeat until in lua

In Lua, the repeat until loop is a type of loop that will continue to execute a block of code until a certain condition is met. Here is an explanation of each step involved:

1. The repeat keyword marks the beginning of the loop block.

2. The block of code that needs to be executed repeatedly is placed after the repeat keyword.

3. The until keyword is used to specify the condition that needs to be met in order for the loop to exit.

4. The condition is evaluated after each iteration of the loop.

5. If the condition evaluates to true, the loop will exit and the program will continue execution after the loop.

6. If the condition evaluates to false, the loop will continue to repeat and execute the block of code again.

To summarize, the repeat until loop in Lua executes a block of code at least once, and then checks a condition at the end to determine whether the loop should continue or exit.
