How to use Object Entries and Array Shuffling In Javascript
Convert the object into an array of key-value pairs using Object.entries() method. Shuffle the array using a shuffling algorithm, like the Fisher-Yates shuffle. Convert the shuffled array back into an object using Object.fromEntries() method.
Example: The below code uses the above-discussed approach to randomly rearrange an object in JavaScript.
Javascript
function shuffleObject(obj) { const entries = Object.entries(obj); for (let i = entries.length - 1; i > 0; i--) { const j = Math.floor(Math.random() * (i + 1)); [entries[i], entries[j]] = [entries[j], entries[i]]; } return Object.fromEntries(entries);}const originalObject = { a: 1, b: 2, c: 3, d: 4 };const shuffledObject = shuffleObject(originalObject);console.log(shuffledObject); |
Output
{ c: 3, a: 1, d: 4, b: 2 }
How to Randomly Rearrange an Object in JavaScript ?
Randomly rearranging an object in JavaScript involves shuffling its properties in a random order. This operation is particularly useful for scenarios where the order of object properties needs to be randomized, such as implementing a randomizer for game elements or shuffling quiz questions.
