Export assignment nativeClass

• nativeClass(v: any): string

• Returns a string value indicating a specification defined classification (via the internal property [[Class]]) of an object.

  Notes

  • The function is not robust for ES2015+ environments. In ES2015+, Symbol.toStringTag allows overriding the default description of an object. While measures are taken to uncover the default description, such measures can be thwarted. While this function remains useful for type-checking, be aware that value impersonation is possible. Where possible, prefer functions tailored to checking for particular value types, as specialized functions are better equipped to address Symbol.toStringTag.

  Parameters

  • v: any

    input value

  Returns string

  string value indicating a specification defined classification of the input value

  Example

  var str = nativeClass( 'a' );
  // returns '[object String]'

  Example

  var str = nativeClass( 5 );
  // returns '[object Number]'

  Example

  function Beep() {
      return this;
  }
  var str = nativeClass( new Beep() );
  // returns '[object Object]'
