An array is a collection of items stored at contiguous memory locations. Each item can be accessed through its index (position) number. Arrays always start at index 0, so in an array of 4 elements we could access the 3rd element using the index number 2. The length property of…

In computer science, a data structure is a data organization, management, and storage format that enables efficient access and modification. More precisely, a data structure is a collection of data values, the relationships among them, and the functions or operations that can be applied to the data. Different types of…

Did you ever wonder how strings, arrays or objects “know” the methods each of them have? How does a string know it can .toUpperCase() or an array that it can .sort()? We never defined these methods manually, right? The answer is that these methods come built-in within each type of…

Constructor functions are functions that are used to construct new objects. The new operator is used to create new instances based off a constructor function. …
