Stage 0 (Strawperson)

What is it? A free-form way of submitting ideas for evolving ECMAScript. Submissions must come either from a TC39 member or a non-member who has registered as a TC39 contributor.

What’s required? The document must be reviewed at a TC39 meeting (source) and is then added to the page with stage 0 proposals.

These stage details are taken from Dr. Axel Rauschmayer's blog post. You can read more about the TC39 process in their official process document.
