If not, what is the problem here? The issue with `?.[` is that it is considered as not pretty by some people. A syntax that is at the same time pretty, technically working, and not confusing is difficult to find. I agree with both points here. It's not very pretty, and it's also inconsistent with the rest of the language. I was just clarifying what I believed to be the primary contender, independent of bias. Concerning your suggestion of using `!`: From a technical point of view, using `![` instead of `?.[` may work only if you forbid a line terminator before the `!`, because the following program is valid as of today (with implied semicolons): ```js foo ![42] ``` I want to like the idea, but many languages (e.g. Swift, Kotlin, and I think TypeScript 2.0) use it in the inverse direction: non-null assertion for nullable types. I'm not sure I like the syntax in either form (it has at least the ability to be non-ambiguous). I’m curious why this proposal is not even listed in stage 0 proposal list. Because no representative of TC39 has volunteered to champion it. —Claude _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
