How to Remove Element from JSON Object in JavaScript ? Last Updated : 16 Apr, 2024 Comments Improve Suggest changes Like Article Like Report In JavaScript, removing elements from a JSON object is important for modifying data structures dynamically. This object manipulation can help us to create dynamic web pages. The approaches to accomplish this task are listed and discussed below: Table of Content Using delete KeywordUsing filter MethodUsing DestructuringUsing delete KeywordIn this approach, we are using the delete keyword to directly remove a specific key from the JSON object. After deletion, the updated object no longer contains the deleted key, as seen when logging the object to the console. Syntax:delete objectName.propertyName;Example: The below example uses the delete keyword to remove an element from JSON object in JavaScript. JavaScript let jObj = { "company": "GeeksforGeeks", "courses": ["DSA", "Web Tech", "Placement_Preparation", "DDA"] }; delete jObj.courses; console.log(jObj); Output{ company: 'GeeksforGeeks' } Using filter MethodIn this approach, we are using the filter method with Object.entries to create an array of key-value pairs, then filtering out the key based on a condition. Finally, we use Object.fromEntries to convert the filtered array back into a JSON object. Syntax:let updatedObject = Object.fromEntries( Object.entries(originalObject).filter( ([key, value]) => /* condition to keep or remove key */));Example: The below example uses the filter Method to remove an element from JSON object in JavaScript. JavaScript let jObj = { "company": "GeeksforGeeks", "courses": ["DSA", "Web Tech", "Placement_Preparation", "DDA"] }; jObj = Object.fromEntries( Object.entries(jObj). filter(([key, value]) => key !== "courses") ); console.log(jObj); Output{ company: 'GeeksforGeeks' } Using DestructuringIn this approach using destructuring, we extract the key from the JSON object into a variable courses while collecting the rest of the object into res. Printing res shows the JSON object jArr without the "courses" key. Syntax:const { propertyToRemove, ...rest } = objectName;Example: The below example uses the Destructuring to remove an element from json object in JavaScript. JavaScript let jArr = { "company": "GeeksforGeeks", "courses": ["DSA", "Web Tech", "Placement_Preparation", "DDA"] }; let { courses, ...res } = jArr; console.log(res); Output{ company: 'GeeksforGeeks' } Comment More infoAdvertise with us Next Article How to Remove Element from JSON Object in JavaScript ?
