JavaScript supports different kinds of loops: The for statement creates a loop with 3 optional expressions: Expression 1 is executed (one time) before the execution of the code block. Expression 2 defines the condition for executing the code block. Expression 3 is executed (every time) after the code block has been executed.

JavaScript now supports five different types of loops: while — loops through a block of code as long as the condition specified evaluates to true. do…while — loops through a block of code once; then the condition is evaluated. If the condition is true, the statement is repeated as long as the specified condition is true.
