bforbis commented on issue #1584: THRIFT-4625: Use let/const variable
decorators in ES6 Javascript
URL: https://github.com/apache/thrift/pull/1584#issuecomment-418155339
It seems like I ran into an issue where I pulled on a thread and unravelled
the entire rug. This requires a decently large overhaul of the test system for
javascript, which is currently relying on a very old version of QUnit which
relies on a now defunct version of PhantomJS.
QUnit has since moved to using puppeteer on top of headless chrome, which
has full ES6 support. The advantage of this is we don't need any transpilation
/ polyfills, but getting the build dependencies installed across all the docker
images is a bit tricky.
I think I've gotten it resolved for ubuntu-bionic, but ubuntu-xenial is
showing some issues (I think due to it having an older version of nodejs)

> let / const variable decorators for es6 compiler
> ------------------------------------------------
>
> Key: THRIFT-4625
> URL: https://issues.apache.org/jira/browse/THRIFT-4625
> Project: Thrift
> Issue Type: Improvement
> Components: JavaScript - Compiler, Node.js - Compiler
> Reporter: Brian Forbis
> Priority: Minor
>
> With support for the ES6 compiler, variables should be scoped using the ES6
> *let* and *const* variable decorators to define variable scoping and
> read/write behavior.
> This brings the generated code into compliance with the
> [no-var|https://eslint.org/docs/rules/no-var] eslint rule.
