TypeScript extracts two functions of JSON

export default class Tools {
  /** * Check whether the object has key *@param obj 
   * @param key 
   */
  objectHasKey(obj: object, key: string | number | symbol) {
    return Object.prototype.hasOwnProperty.call(obj, key);
  }

  /** * get values * of the object@param * / object obj
  objToArray(obj: object) {
    const values = [];
    for (const value of Object.values(obj)) {
      values.push(value)
    }
    returnvalues; }}Copy the code
