I really like the capabilities provided by libraries such as ts-pattern, and I'd love to see pattern matching become a native JavaScript feature. Is the proposal making meaningful progress through TC39, and is there enough support for it to eventually move forward?

For now, destructuring, if statements, and regular switch statements cover many practical cases. They’re less elegant than dedicated pattern matching, but they’re available today and don’t add another major syntax system for developers to learn.
The proposal is currently at Stage 1, so it’s still very early. I wouldn’t expect it to arrive in JavaScript anytime soon—possibly not for many years.
There does seem to be interest from some TC39 delegates, but the proposal has had a rough history. Work has stalled and restarted before, and it covers a lot of syntax and behavior. That makes it more difficult to advance, especially while TC39 is cautious about adding large new features to the language. It could eventually happen, but the proposal would first need active champions and sustained development again.
