VariableDeclaratorBase

Interface Code

   * Whether there's definite assignment assertion (`let x!: number`).
   * If `true`, then: `id` must be an identifier with a type annotation,
   * `init` must be `null`, and the declarator must be a `var`/`let` declarator.
   */

   * The name(s) of the variable(s).
   */

  /**
   * The initializer expression of the variable. Must be present for `const` unless
