A **loop** is the repetitive execution of a piece of code for a given amount of repetitions or ​until a certain condition is met. For instance, if a string is to be printed *five times* it can be done by typing five print statements; but, it is easier to set-up a loop to execute the *same* block of code *five times*.

# Different types of loops (Ruby)

 

## While Statement


The **while statement** executes a code repeatedly ​as long as the condition is true. 

>A while loop's conditional is separated from the code by the reserved word `do`, a newline, a backslash (`\`), or a semicolon.

## Syntax

## Code

See the example below of how to write a `while` loop in Ruby:

a = 1
b = 6
while a < b do
 print a ,": Welcome to Educative.\n"
 a +=1 
 end

# While modifier

`begin` and `end` can also be used to create a while loop.

## Syntax

## Code

See the example below of how to write a `begin`/`end while` loop in Ruby:

x = 1
begin
 print x ,": Welcome to Educative.\n"
 x += 1
end while x < 6

# Until statement

The **until loop** executes while the condition is false. 

> An until loop's conditional is separated from the code by the reserved word `do`, a newline, backslash (`\`), or a semicolon.

## Syntax

## Code

See the example below of how to write an `until` loop in Ruby:

x =  1
y =  5
until x > y  do
  print  x ,": Welcome to Educative.\n"
  x +=1 
end

# Until modifier

Like the while modifier, `begin` and `end` can also be used ​to create an until loop.

## Syntax

## Code

See the example below of how to write a `begin`/`end until` loop in Ruby:

x = 1
begin
  print  x ,": Welcome to Educative.\n"
  x += 1
end until x > 5

# For statement

The for loop consists of `for`, followed by a variable to contain the iteration argument, followed by `in`, and the value to iterate over using `each`.

## Syntax

for variable [, variable ...] in expression [do]
   code
end

## Code

See the example below of how to write a `for` loop in Ruby:

for x in 1..5
  print  x ,": Welcome to Educative.\n"
end
