描述

lib Update Request

Configuration Check

My compilation target is ES2015 and my lib is the default.

Missing / Incorrect Definition

Array and other interfaces for built-ins do not declare their own constructor methods

Sample Code

[].constructor[Symbol.species];
Element implicitly has an 'any' type because expression of type 'unique symbol' can't be used to index type 'Function'.
  Property '[SymbolConstructor.species]' does not exist on type 'Function'.

The code compiles fine when defining the appropriate constructor method:

declare global {
  interface Array<T> {
    constructor: ArrayConstructor;
  }
}
