Today, let’s explore a code snippet to understand how the array length behaves when we manipulate the array in non-conventional ways: Code Snippet: 1. Initializing the Array: Here, we initialize an array numbers with three elements: 1, 2, and 3. In JavaScript, arrays are zero-indexed, meaning the first element is at index 0, the second […]
In JavaScript, arrays are a common data structure used to store collections of elements.

At first glance, this code might look like it would simply add a 10 to the end of the array, but there’s more going on […]
If you’ve ever encountered the expression console.log({} + []) in JavaScript, you might have been confused by the result: “[object Object]”. The combination of {} (an empty object) and [] (an empty array) doesn’t seem intuitive, but there’s a good explanation for why JavaScript behaves this way. Let’s dive into the reasoning behind this seemingly […]
