zent/utils/isPromise.js

一套前端设计语言和基于React的实现

'use strict';

Object.defineProperty(exports, "__esModule", {
  value: true
});

var _typeof = typeof Symbol === "function" && typeof Symbol.iterator === "symbol" ? function (obj) { return typeof obj; } : function (obj) { return obj && typeof Symbol === "function" && obj.constructor === Symbol && obj !== Symbol.prototype ? "symbol" : typeof obj; };

exports['default'] = isPromise;
/**
 * Test whether an object looks like a promise
 *
 * @export
 * @param {any} obj
 * @returns {bool}
 */
function isPromise(obj) {
  return !!obj && ((typeof obj === 'undefined' ? 'undefined' : _typeof(obj)) === 'object' || typeof obj === 'function') && typeof obj.then === 'function';
}
module.exports = exports['default'];
