code reuse

As developers, we often find ourselves solving similar problems time and time again. Luckily, we have discovered a way to make our lives easier through the use of libraries. These libraries contain pre-written code that can be reused and shared among developers, allowing us to save time and effort in our programming tasks. Arduino, a popular platform for building electronic projects, also offers a wide range of libraries that can enhance our projects....

In JavaScript, you can divide a program into separate files to improve organization and reusability. But how do you make the functions defined in one file accessible to other files? In this article, we will explore how to export multiple functions from a JavaScript file. Let’s say you have a JavaScript file where you define a few functions, like this: function sum(a, b) { return a + b; } function mul(a, b) { return a * b; } To make these functions available to other files, you can use the export keyword....
