Port harmony issue queue about terser HOT 6 CLOSED

I would be willing to help with that -- it would give others a good task list of things to work on as well.

from terser.

@toddself please feel free to go ahead with this - perhaps with something like a "[uglify-es]" prefix or similar to make these easy to distinguish, although ideally we should have a new label for this.

Most open harmony bugs have already been fixed in @fabiosantoscode/uglify-es. Please verify that a given bug still exists before creating a ticket. Please follow this project's new issue template with an unambiguous succinct test case producing bad output once minified with certain options.

I wouldn't bother porting feature requests and non-bugs. Individuals can open such tickets in this project.

Thanks to the hard work from @kzc and @fabiosantoscode it looks like the only remaining bugs in the uglify-js that aren't marked as resolved in the threads are:

• mishoo/UglifyJS#2696
• mishoo/UglifyJS#2662
• mishoo/UglifyJS#1372

The first two seem to be low priority/edge cases. The last one involves the test262 feature set. Are these even worth porting over?

from terser.

@toddself Thanks. Like you say those are obscure edge cases. I think users can report issues to this project as they arise.

Other known issues with uglify-es and this fork:

• TDZ - mishoo/UglifyJS#2750
• ES6 block scope issues for classes and functions

$ echo 'while(0){function foo(){console.log("FOO")}} foo();' | bin/uglifyjs --toplevel -c | node
FOO

$ echo 'while(0){function foo(){console.log("FOO")}} foo();' | node0_10_41 
FOO

$ echo 'while(0){function foo(){console.log("FOO")}} foo();' | node0_12_9 
FOO

$ echo 'while(0){function foo(){console.log("FOO")}} foo();' | node421
FOO

$ echo 'while(0){function foo(){console.log("FOO")}} foo();' | node621 
[stdin]:1
while(0){function foo(){console.log("FOO")}} foo();
                                             ^
TypeError: foo is not a function

Functions and classes still incorrectly follow ES5 scope rules as node versions 0.10, 0.12 and 4.x did.

No need for this ticket now that people are becoming more familiar with the Terser project.
