Difference between Array and Object | JavaScript Tutorials in Hindi | Interview Question #23 Hi, I'm Rohit Verma, Welcome to our YouTube Channel Still Learning. About this video :- In JavaScript, arrays and objects are both used to store collections of data. However, there are some key differences between them: Structure: An array is an ordered collection of values, while an object is an unordered collection of key-value pairs. Accessing elements: In an array, elements can be accessed using their numeric index, starting from 0. In an object, elements can be accessed using their keys. Size: Arrays have a length property that tells you the number of elements in the array. Objects do not have a length property, but you can use the Object.keys() method to get an array of the keys in the object, and then use the length property on that array to get the number of keys. Type: Arrays are a specific type of object in JavaScript. You can use the Array.isArray() method to check if a given variable is an array. Overall, arrays are used to store ordered collections of data, while objects are used to store unordered collections of data that are accessed using keys.
