Do-While Loop in Ruby
The while loop executes a block of code while a boolean expression evaluates to true. It checks the boolean expression after each iteration. It terminates as soon as the expression evaluates to false.
loop do #code to be executed break if booleanExpression end
Because the do-while loop evaluates the boolean expression at the end of the iteration, the block of code within the loop is guaranteed to run at least once.
booleanExpression results in either a true or false output. It is created using comparing operators (==, >, =, <=, !=).
There can also be multiple boolean expressions within the parentheses (booleanExpression). The boolean expressions are connected through logical operators (&&, ||, !).
x = 0 loop do x++ break if x > 100 end
