Deconstruction assignment es6- objects and arrays

      // 1. Test objects destructuring assignment 
      const object1 = {A1: ' A1 ' , B1: ' B1 ' };
       const {A1, B1, C1} = object1; 
      the console.log (A1, B1, C1);

       const [A2, B2, C2] = arr2 is; 
      the console.log (A2, B2, C2); 
      // 3. destructuring assignment function test - mass Object 
      const object3 {A3 =: ' A3 ' , B3: ' B3 ' };
      the this .testObject (object3);
       // 4. destructuring assignment function test - pass array 
      const arr4 = [ ' A4 ' , ' B4 ' ];
       the this .testArray (arr4);
