Ensure using `es6` for `web3.min.js`

Muhammad-Altabba commented 10 months ago

Expected behavior

web3.min.js has syntax compatible with es6.

Actual behavior

The minified build (web3.min.js) contains the syntax ?. which is called Optional Chaining (https://2ality.com/2019/07/optional-chaining.html), that is es2020 which is far from es6 (ES2015).

Steps to reproduce the behavior

Check: https://github.com/web3/web3.js/issues/6472#issuecomment-1754098689
