External module "assert/is-type-error/docs/types/index.d"

Export assignment isTypeError

• isTypeError(value: any): boolean

• Tests if a value is a TypeError object.

  Notes

  • This function should not be considered robust. While the function should always return true if provided a TypeError (or a descendant) object, false positives may occur due to the fact that the TypeError constructor inherits from Error and has no internal class of its own. Hence, TypeError impersonation is possible.

  Parameters

  • value: any

    value to test

  Returns boolean

  boolean indicating whether a value is a TypeError object

  Example

  var bool = isTypeError( new TypeError( 'beep' ) );
  // returns true

  Example

  var bool = isTypeError( {} );
  // returns false
