JavaScript 2.0

March 1999 Draft

JavaScript 2.0

Thursday, March 25, 1999

Introduction

JavaScript 2.0 is an experimental proposal maintained by waldemar for future changes in the JavaScript language. At this stage the emphasis is on developing the broad concepts of the language; many of the details will be worked out later. The eventual language may differ significantly from this proposal, but the goal is to move in the directions indicated here and do so via a coordinated plan rather than adding miscellaneous features ad hoc on a release-by-release basis.
