What Is A Function In Javascript by xutini: 5:42am On Feb 16, 2023 |
https://www.youtube.com/watch?v=8OzR6vhTKx0 In computer programming, a function is a reusable block of code that performs a specific task. It is a self-contained unit of code that can be called from other parts of a program, and can be passed input values (called arguments or parameters) and return output values. Functions are an essential building block in most programming languages, and they provide a way to break down a program into smaller, more manageable pieces of code. Functions can be used to perform a wide range of tasks, from simple calculations to complex operations, and can be used to build up more complex programs from simpler components. Here's an example of a simple function in JavaScript that takes two parameters and returns their sum:
In this example, addNumbers() is a function that takes two parameters, a and b, and returns their sum using the + operator. The function can be called from other parts of the program, like this:
In this example, the value of result would be 5, which is the sum of 2 and 3 passed in as arguments to the addNumbers() function. Functions can be used to perform many different kinds of tasks, from simple calculations to complex data processing and manipulation. They provide a way to encapsulate code into reusable units, and make programs easier to understand and maintain. I have created a video to explain these concepts.
