Lua Programming/How to Lua/repeat

A repeat loop is a conditional loop construct that repeatedly executes a block of instructions whilst the condition is true. The repeat statement is used together with an until syntactical cocomponent to produce a repeat loop:

attempts = 0
repeat
  print "Knock! Knock!"
  attempts = attempts + 1
until attempts == 10

The block of code within a repeat loop will always run at least once

Note than unlike while loops, with a repeat loop, the condition is evaluated after the block within the loop. This means that the block of code within a repeat loop will always run at least once.
