Append Object To Object Javascript Code Example

Example 1: append object to object javascript

// Spread syntax allows an iterable (in this case an object) to be expanded  const originalObj = { name: 'John', age: 34 } let newObj = { ...originalObj, city: 'New York' } // newObj is now { name: 'John', age: 34, city: 'New York' }  // it can also be used with the same object newObj = { ...newObj, language: 'en' } // { name: 'John', age: 34, city: 'New York', language: 'en' }

Example 2: object javascript append

var list = [];  list.push({name:'John', last_name:'Doe'}); list.push({name:'Jane', last_name:'Doe'});  console.log(list); /* Result: [   {     "name": "John",     "last_name": "Doe"   },   {     "name": "Jane",     "last_name": "Doe"   } ] */

How about storing the alerts as records in an array instead of properties of a single object ?  var alerts = [      {num : 1, app:'helloworld',message:'message'},     {num : 2, app:'helloagain',message:'another message'}  ] And then to add one, just use push:  alerts.push({num : 3, app:'helloagain_again',message:'yet another message'});

Example 4: javascript append to object

var alerts = [      {num : 1, app:'helloworld',message:'message'},     {num : 2, app:'helloagain',message:'another message'}  ]

Example 5: javascript append to object

alerts.push({num : 3, app:'helloagain_again',message:'yet another message'});
