KeywordsA keyword is an identifier-like sequence of characters that is reserved, and cannot be used as an identifier except when prefaced by the @ character. keyword: one of In some places in the grammar, specific identifiers have special meaning, but are not keywords. Such identifiers are sometimes referred to as “contextual keywords”. For example, within a property declaration, the “get” and “set” identifiers have special meaning (§10.7.2). An identifier other than get or set is never permitted in these locations, so this use does not conflict with a use of these words as identifiers. In other cases, such as with the identifier “var” in implicitly typed local variable declarations (§8.5.1), a contectual keyword can conflict with declared names. In such cases, the declared name takes precedence over the use of the identifier as a contextual keyword.
