Browsers Runtime Environment

Using JavaScript on your browser.

Browser Runtime Env

The code we have been running relies on an environment. The most common one, known as the front end, is the browser.

The issue here is we need the browser to run Javascript or use other programming languages like Java or PHP.

Thank to NODE, this had changed.

The power of Javascript expanded

The Node environment allows us to create code without a browser, meaning we can create full-stack software.

As you can see, this code to your right is running on a PowerShell!

The power of flexible and reusable code.

Modules allow us to add code in a special way. It allows us to segment our programs in a way that allows us to work more effectively in groups and debug our code.

It would be nice if someone who is amazing with math, makes all the math modules we need for our program. While we focus on other parts like the database module!

Benefits of using Modules

• Compose Software: Using modules like lego blocks, building parts of the program. E.G, we have a team of programmers; one builds the house, another builds a car.

• Isolate components: The programmers can build the module that needed for the project without usually thinking about the entire codebase. E.G, one programmer makes a lego car, there no need for him/her/they to worry about the housing module yet...

• Organized code: Modules tend to be more organized for the main codebase.

• Reuse code: Modules make it really easy to reuse the same code, even one more than one project.

Demo Time

On slide 4, we used node to run the meal maker. It would be a waste not to use it again in a new program that I like to call the Meal of the day!
