ES2022 - terser can not handle syntax ( SyntaxError: Unexpected token: punc ({) )

[AdamKundracik]

Hi everyone,

Today I was challenging this error during run of app build script

Error: Optimization error [libs_frontend_core_widgets_divider_src_index_ts.cb12a303421ad2b8.js]: SyntaxError: Unexpected token: punc ({)

First I was thinking it's just package problem but nothing could fix it.

Then I found guy, having same issue as me on stack overflow.

HOW TO FIX IT?

1. Go to you tsconfig.json
2. search for "target"
3. Change it to ES2020 (Worked for me)
4. Enjoy working build

Hopefully this help someone because I cried for 5 hours fixing this
