JavaScript Lint 0.1k Released

Sat, 24 Dec 2005 18:56:35 +0000

This release includes a number changes.


  • JavaScript Lint warns if the default case is not at the end of the switch statement.

  • Control comments can now use the /*jsl:keyword*/ syntax in addition to the /*@keyword@*/ syntax. The new syntax is recommended for interoperability with JScript conditional compilation, although the traditional syntax is still supported.

  • The "missing break" warning can be disabled for the last case in a switch statement. The presence of this break is merely stylistic preference.

  • The "missing semicolon" warning can be disabled when anonymous functions are assigned to variables and properties (such as function prototypes). Code such as the following can optionally be allowed:

    function Coord() {
        this.x = function() {
            return 1;

    Coord.prototype.y = function() {
        return 0;

Bug Fixes:

  • The "undeclared identifier" warning for variables has been updated to reflect the ECMA specification. The following code no longer issues a warning:

    function getX() { return x; }
    var x;

  • Scripts with circular import directives no longer incorrectly report undeclared identifiers.
