How to get a subset of a javascript object's properties?

To get a subset of object's properties and create a new object out of those properties, use object destructuring and property shorthand. For example, You have the following object −

Example

const person = {    name: 'John',    age: 40,    city: 'LA',    school: 'High School' }

And you only want the name and age, you can create the new objects using −

const {name, age} = person; const selectedObj = {name, age}; console.log(selectedObj);

Output

This will give the output −

{    name: 'John',    age: 40 }
