How to Create a Multidimensional Associative Array in JavaScript?

Estimated read time 2 min read

In JavaScript, you can create a multidimensional associative array by creating an array of objects. Each object can represent a sub-array and have its own set of properties, which can in turn be arrays or objects.

Here’s an example of how you could create a 2-dimensional associative array in JavaScript:

let multidimensionalArray = [  {    name: 'John',    age: 30,    hobbies: ['reading', 'traveling']
    name: 'Jane',
    age: 28,
    hobbies: ['painting', 'cooking']


In this example, the multidimensionalArray variable is assigned an array of objects, where each object represents a sub-array with properties for name, age, and hobbies. To access the values in the array, you can use bracket notation and specify the index of the sub-array and the name of the property you want to access, just like you would with a normal object. In this case, the first element of the multidimensionalArray is accessed using multidimensionalArray[0]['name'], which returns the value 'John', and the second hobby of the second sub-array is accessed using multidimensionalArray[1]['hobbies'][1], which returns the value 'cooking'.

You can use this approach to create multidimensional associative arrays with as many dimensions as you need, depending on the requirements of your use case. Just keep in mind that working with large, complex arrays can make your code more difficult to read and maintain, so it’s important to choose the right data structure for your problem and to design your arrays in a way that makes sense for your specific use case.
