"Five years ago" refers to across-the-board browser support, the spec is older. You can use caniuse.com, https://kangax.github.io/compat-table/es6/ https://kangax.github.io/compat-table/es6/, and/or MDN compatibility tables to quickly check browser support. Browsers are now grinding away at new APIs constantly - don't let your memory of "not safe to use" last more than a year.
- couchand 9y agoIt may be hard to imagine, but even today not every user is running a browser built in the last year.
- hnzix 9y agoCorporate and government SOE machines are often running versions 7+ years out of date. I'm still EOL'ing XP machines for government clients. Seniors are another group who often run, well, senior versions. If your Uber-for-toothpaste startup doesn't care then fine. But crusty old browsers are still a crucial factor in many markets.

- twhb 9y agoIf you explore the first of the links you're replying to, you'll see that I make my conclusions about what people are using based on country-adjusted analytics from millions of websites, not imagination. This situation is actually improving too. Chrome's "evergreen" development cycle has made a world of difference to feature adoption rate, and it's spread to every other major browser vendor. Once IE11 dies out, we'll have no non-evergreen browsers over 1% market share, and it makes me so happy to say that.
