How can someone actually change JavaScript?
In a Nutshell
Anyone can influence JavaScript by participating in TC39 proposal discussions on GitHub, writing tests in the test262 suite, or convincing a committee member to champion an idea. Official membership requires an employer to join ECMA International, but non-members can still contribute meaningfully through public feedback and testing. Student contributions demonstrate that practical involvement in the specification process is accessible beyond formal committee roles.

When the JavaScript committee considers proposals, they follow a well-defined process. The process has several stages ranging from an idea that is just an idea to the final stage, which means that a proposal actually becomes a part of the JavaScript standard.
You can participate in the work of the committee, for example, by following the discussions in the GitHub repositories for proposals. Every proposal has a GitHub repository. It's all open. It's all public. You can follow. You can comment. And the committee actually cares about the feedback from the language community, from the developers.
If you have some idea for a feature and you are able to convince a member of the committee to actually champion it, then that person can present it to the entire committee. And if the committee thinks that it is interesting, they could consider it.
If you are serious about contributing, you can basically join the committee, but it's not on an individual basis. Only organizations can be members. So, your employer can join ECMA International, the standardization organization, and then they will have access to TC39. They could be able to attend meetings and to actually participate in technical decision-making.
But even without joining the committee officially, you can still contribute. For example, you can write tests in the test262 testing suite. Every proposal has that. And it's actually a requirement to have the testing suite done for a proposal to advance along the TC39 process.
