How to use splice on Nested Array of Objects ? Last Updated : 23 Feb, 2024 Comments Improve Suggest changes Like Article Like Report Using the splice() method on a nested array of objects in JavaScript allows you to modify the structure of the nested array by adding or removing elements at specified positions. Table of Content Accessing the nested array directlyUtilizing a combination of array methodsAccessing the nested array directlyThis approach directly accesses the nested array within each object using dot or bracket notation and applies the splice() method to modify the nested array. Example: The below example implements the splice() method to access the nested array elements in JavaScript. JavaScript let nestedArray = [ { id: 1, items: [1, 2, 3] }, { id: 2, items: [4, 5, 6] } ]; // Removing element at index 1 from the // nested array within the first object nestedArray[0].items.splice(1, 1); console.log(nestedArray); Output[ { id: 1, items: [ 1, 3 ] }, { id: 2, items: [ 4, 5, 6 ] } ] Utilizing a combination of array methodsThis approach involves first finding the index of the object containing the nested array using methods like findIndex(), then applying splice() to the nested array within that object. Example: The below example Utilizes a combination of array methods with array of objects in JavaScript. JavaScript let nestedArray = [ { id: 1, items: [1, 2, 3] }, { id: 2, items: [4, 5, 6] } ]; let index = nestedArray.findIndex( obj => obj.id === 1); // Removing element at index 1 from the // nested array within the object with id 2 if (index !== -1) { nestedArray[index].items.splice(1, 1); } console.log(nestedArray); Output[ { id: 1, items: [ 1, 3 ] }, { id: 2, items: [ 4, 5, 6 ] } ] Comment More infoAdvertise with us Next Article How to use splice on Nested Array of Objects ?
