Loops in JScript

  • Article

JScript includes several ways to execute a statement or block of statements repeatedly. In general, repetitive execution is called looping or iteration. An iteration is simply a single execution of a loop. It is typically controlled by a test of a variable, where the value is changed each time the loop is executed. JScript supports four types of loops: for loops, for...in loops, while loops, and do...while loops.

In This Section

    Discusses how JScript uses for loops and provides some practical examples.

  • for...in Loops
    Describes the concept of for...in loops and explains how to use them in JScript.

  • while Loops
    Discusses the two types of while loops and explains how they differs from for loops.

  • break and continue Statements
    Describes how to use the break and continue statements to override the behavior of a loop.

  • JScript Conditional Structures
    Describes how JScript normally handles program flow and provides links to information that explains how to regulate the flow of a program's execution.

  • JScript Reference
    Lists elements that compose JScript Language Reference and links to topics that explain the details behind the proper use of language elements.
