@learnmove just a question, is the Untitled doc set as plaintext?

[learnmove]

I found when I set jquery.js syntax as not javascript ,it move cursor fast
move cursor faster than original javscript syntax,when turn to actionscript

Long lines don't fare well with how ST and other editors using syntax highlighting based on TextMate optimize their highlighting. I believe we have an issue for bad performance in long lines, but I was unable to find it.

In my personal case, I feel serious lag while moving cursor after opening jquery.js.

A plugin profile shows that TypeScript is consuming unreasonable time. After disabling TypeScript, the lag disappears immediately... I found a guy ran into the same issue microsoft/TypeScript-Sublime-Plugin#716

@learnmove try reverting to a clean state to see if the issue is still there: https://www.sublimetext.com/docs/3/revert.html

If it's not, either a third-party plugin or syntax definition show bad performance.

I found issue
when I search method
like @css
it is mess,and all screw up
but normal js it can find

maybe original javascript syntax only support normal javascript,not jquery code style

package 'javascript next' support

I would suggest you provide a screenshot if you cannot properly describe what is actually happening. I don't think people know what "mess / screw up" actually means.

By the way, I don't think there is a point using Javascript Next since the built-in Javascript should have supported ES6. (No?)

I feel you are using ctrl+shift+r rather than ctrl+r?
