TSLint and VSCode Issues: All destructured elements are unused
Error 1:
Type assertion using the '<>' syntax is forbidden. Use the 'as' syntax instead. (no-angle-bracket-type-assertion)tslint(1)
This assertion is unnecessary since it does not change the type of the expression. (no-unnecessary-type-assertion)tslint(1)
'SchemaForm' refers to a value, but is being used as a type here.ts(2749)
Error 2:
All destructured elements are unused.
Error 3
Cannot find name 'container'.
What settings gone missing?
VSCode: Latest Version
OS: Mac Catalina 10.15.3
Solution
JSX syntax is only valid in a .tsx file. Since you are in a .ts file, typescript will try to interpret the <> as a type assertion not a JSX tag, and parsing goes bad from there. Change the extension and it should work
