Class AST::ValueNode

A program element that evaluates to a value or destructures a value at runtime. This includes expressions and destructuring patterns, but also function and class declaration statements, as well as TypeScript namespace and enum declarations.

Examples:

0                               // expression
(function id(x) { return x; })  // parenthesized function expression
function id(x) { return x; }    // function declaration
