  • eval() is now a method of every object (was previously a built-in function); it evaluates a string of JavaScript code in the context of the specified object.
  • Math.random() now works on every platform.
  • toString(): Added radix parameter, which specifies the base to use for representing numeric values.
  • isNaN() now works on every platform (not only Unix anymore)
  • parseFloat() and parseint() now return NaN on all platforms, if the first character of the specified string cannot be converted to a number; in previous releases, it returned NaN on Solaris and Irix and zero on all other platforms.
