1# babel-preset-stage-1
2
3> Babel preset for stage 1 plugins.
4
5The gist of Stage 1 is:
6
7> **Stage 1**: proposal
8>
9> **What is it?** A formal proposal for the feature.
10>
11> **What’s required?** A so-called champion must be identified who is responsible for the proposal. Either the champion or a co-champion must be a member of TC39 (source). The problem solved by the proposal must be described in prose. The solution must be described via examples, an API and a discussion of semantics and algorithms. Lastly, potential obstacles for the proposal must be identified, such as interactions with other features and implementation challenges. Implementation-wise, polyfills and demos are needed.
12>
13> **What’s next?** By accepting a proposal for stage 1, TC39 declares its willingness to examine, discuss and contribute to the proposal. Going forward, major changes to the proposal are expected
