get string content

Error message

get string content

What it means

Panic inside KnownMemberExpressionProperty::name: for expression elements the method extracts static string content (identifier name, string literal, or a template quasi's cooked text) and an internal expect("get string content") fires when a template-literal element has no usable quasi content. The method returns Option, so callers like is_name_equal already treat None as "no static name".

Solutions

1. Handle the computed/template element case explicitly and return None instead of unwrapping quasi content
2. Guard with a check that the template has exactly the expected quasis before extracting text
3. Keep matchers limited to identifier and string-literal property elements
