JavaScript Lint 0.1k Released

This release includes a number changes.

Enhancements:

• 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.
