Just curious. Is there a reason template literals are not allowed as property
names in object literals? I can do:
let obj = {'foo bar': 1};
and
let obj = {"foo bar": 1};
but not
let obj = {`foo bar`: 1};
It doesn't seem that allowing the latter would present any syntactic problems
and seems like almost an oversight that it's not allowed.
The main reason I ask is that we've gone completely over to using template
literals for all our literals (why not?) and was surprised that we can't use a
template literal as an object literal property name. Obviously, we can do:
let obj = {[`foo bar`]: 1};
And given that square brackets allow arbitrary expressions for propery names,
it wouldn't seem that supporting template literals for object literal property
names would not present any daunting implementation issues.
I guess I'd argue that the Principle of Least Astonishment and/or completeness
suggests that JS should support this.
Sorry if this has been asked before but couldn't find anything in the archive.
Thanks
