\
[x] = [1, 2, 3]
\class Test {
[x] = [1, 2, 3]
}Destructuring?
Computed property
Same syntax, very different semantics
-
bad to novices,
-
bad to programmers from other languages,
-
also bad to professional JS programmers
-
rarely known,
-
rarely used,
-
hard to recognize
TypeScript already support it years?
NO
TS 2.7+ (Jan 31, 2018)
Possible solution
New ESLint rule, no-class-computed-field
- Well-known symbols are for methods/accessors,
- Private fields instead of symbol-based private
No big use case
Just drop it!
