How to get a subset of a javascript object's properties? Last Updated : 21 Nov, 2021 Summarize Comments Improve Suggest changes Share Like Article Like Report To get the subset of properties of a JavaScript Object, we make use of destructuring and Property Shorthand. The destructuring assignment syntax is a JavaScript expression that makes it possible to unpack values from arrays, or properties from objects, into distinct variables.Syntax: subset = (({a, c}) => ({a, c}))(obj); Example1: Get subset of a javascript object's properties using destructuring assignment. html <!DOCTYPE html> <html> <head> <title> Get a subset of a javascript object’s properties </title> </head> <body> <center> <h1 style="color:green"> GeeksforGeeks </h1> <h2> Get a subset of a javascript object’s properties </h2> <script> obj = { property1: 5, property2: 6, property3: 7 }; subset = (({ property1, property3 }) => ({ property1, property3 }))(obj); var output = 'Subset Object: <br>'; for (var property in subset) { output += property + ': ' + subset[property] + ';<br>'; } document.write(output); </script> </center> </body> </html> Output: In ES6 there is a very concise way to do this using destructing. Destructing allows you to easily add on to objects and make subset objects.Syntax: const {c, d, ...partialObject} = object; const subset = {c, d}; Example 2: Get subset of a javascript object's properties using destructuring assignment. html <!DOCTYPE html> <html> <head> <title> Get a subset of a javascript object’s properties </title> </head> <body> <center> <h1 style="color:green"> GeeksforGeeks </h1> <h2> Get a subset of a javascript object’s properties </h2> <script> const object = { property1: 'a', property2: 'b', property3: 'c', property4: 'd', } const { property1, property4, ...pObject } = object; const subset = { property1, property4 } ; var output = 'Subset Object: <br>'; for (var property in subset) { output += property + ': ' + subset[property] + ';<br>'; } document.write(output); </script> </center> </body> </html> Output: Comment More infoAdvertise with us Next Article How to implement a filter() for Objects in JavaScript ?
