This course is designed to start you on a path toward future studies in web development and design, no matter how little experience or technical knowledge you currently have. The web is a very big place, and if you are the typical internet user, you probably visit several websites every day, whether for business, entertainment or education. But have you ever wondered how these websites actually work? How are they built? How do browsers, computers, and mobile devices interact with the web? What skills are necessary to build a website? With almost 1 billion websites now on the internet, the answers to these questions could be your first step toward a better understanding of the internet and developing a new set of internet skills. By the end of this course you’ll be able to describe the structure and functionality of the world wide web, create dynamic web pages using a combination of HTML, CSS, and JavaScript, apply essential programming language concepts when creating HTML forms, select an appropriate web hosting service, and publish your webpages for the world to see. Finally, you’ll be able to develop a working model for creating your own personal or business websites in the future and be fully prepared to take the next step in a more advanced web development or design course or specialization.

Creating Web Applications

In our final module, we're going to explore the basics of designing web applications - programming useful and dynamic webpages that allow our users to interact with them. By the end of this lesson you'll be able to: distinguish between client and server-side development; apply advanced JavaScript programming skills to create logic with selection and iteration; create new features for applications; create more advanced HTML forms; and practice and learn additional troubleshooting and problem-solving techniques. The module wraps with a final peer review activity that will draw upon all of the skills you've learned in this course.

Hi, and welcome back.

In our last lesson, we looked at JavaScript loops,

specifically while loops and for loops.

In this lesson, we'll look at an approach to creating new features in your software.

First of all, I want to recommend that you spend a lot of time looking at other

people's web pages and software.

And when you're doing this, don't be passive.

It's important to be curious.

Try to figure out how it works.

Where you can, look at the code.

If you recognize a feature, great.

If you don't recognize it, try to learn something new about it.

When you find things you like, try developing a version of that for yourself.

After you think you've imitated it well, try then to vary it and

make it your own feature.

You're going to face some difficult problems while you're developing software,

particularly when you're developing something that you haven't tried before.

The best way to deal with this in my experience is to break down

your problem into very small parts.

Now, the reason for

this is because very small problems are easier to solve than large problems.

But for some reason when we're developing software, particularly early on

in our experiences, we try to tackle problems that are too large.

So similar to say, for instance, cooking a very large meal for

a company or making a side dish.

It's easier to make a side dish and we can practice it more readily.

But if we try to make a very meal for a large group of company and

we haven't done it before, it's not likely to go well.

And it's the same thing you'll find with developing software.

So make the problems just as small as you possibly can and

tackle those small problems, and then build those into bigger solutions.

When you can, work on your projects with other people and

talk about your challenges.

What's often true is somebody else has faced your problem and

they know a solution, and they can help you, and you may have faced a problem

they're facing now, and you know a solution, and you can help them.

Whenever you have an opportunity to, you should teach and learn from others.

This will cement your skills as a web developer.

It's important to continue to study and practice.

This field changes all the time.

There's always more to learn and practice is a necessity.

Lastly, it is very important to be stubborn and refuse to give up.

I say this, because in this course, you've probably faced a few programs and

exercises that you thought were difficult.

If you're here at this point, you've been stubborn and you haven't given up.

Keep that up, because the problems are fierce at times and

it is really worthwhile to give it your best effort.

And eventually, through determination, win.

In our next lesson, we'll be looking at some guided practice for

our HTML forms and form validation.
