Summary
Regular expression is slow, removing them in escapeHtml should make things faster
I did similar change in vue at first: vuejs/core#12507 (comment)
Then I took a look at react and found vue copied react's implementation, then why not let react have this improvement too?
How did you test this change?
Some simple benchmark by me and @Justineo
https://jsbench.me/rqm4ehfndc/1, shows for simple cases, it's 2x~3x faster
https://jsben.ch/pbGau, shows for random string, it's 1.1x faster
Also cc @aickin, who refactor escapeHtml 8 years ago, maybe you might have interest in this PR too
