Contract
- isKeyword returns true for standard JavaScript reserved keywords including control flow, declaration, and literal keywords
- isKeyword returns true for JavaScript operator and expression keywords such as typeof, instanceof, void, delete, new, this, and in
- isKeyword returns false for regular non-reserved identifier names
- isKeyword returns false for uppercase or mixed-case variants of keywords because JavaScript keywords are case-sensitive
