The JS Foundation is just the rebranded jQuery Foundation. Despite its name the jQuery Foundation already had a much broader scope than just jQuery (e.g. also Dojo).
The JS Foundation is not related to TC39, the organization in charge of new ECMAScript editions. I guess they might sponsor a TC39 member eventually and engage in JS advocacy beyond merely supporting JS open source projects -- similar to what the PSF and its affiliates do for Python.
