Bugfixes#

Escapes in string literals (#1227)#

This was a regression caused by some works related to span (and sourcemaps). I fixed it and swc can emit es5 code as before.

Panic on aliased reexports (#1307)#

This is a regresssion caused by promoting namespaced re-exports like (export * as foo from 'foo') to es2020 from esnext. This is now fixed.

Private class properties (#1306)#

swc previously miscompiled

class Animal {
readonly #name: string;
constructor(name: string) {
this.#name = name;
}
public noise() {
return this.#name.toUpperCase();
}
}

but now swc compiles it correctly. Actaully the fix was addition of one line.

Preserve imports (#1134)#

This is also a regression, but it's now fixed.

Features#

Support for typescript namespace (#1325)#

swc now supports typescript namespace.
