Milestone
Description
The --strictNullChecks
PR changed some declarations in types.ts
to avoid frequent assertions in the compiler's code. Unfortunately these changes make it really unsafe for API users because they no longer contain the actually nullable types: #22088 (comment) #22088 (comment)
ts.Node#parent
is no longer optional (which is definitely wrong forSourceFile
)ts.Symbol#declarations
andts.Symbol.valueDeclaration
are no longer optional, but can still be undefinedts.Type#symbol
is no longer optional, but I guess this comment is still up to date:// Symbol associated with type (if any)
These changes should either be reverted or replaced in the published declaration files.
