To make a web app, you go through seven main stages. Here's how it works:
Stage 1: Figure out what you need
Stage 2: Make basic sketches of your app
Stage 3: Make it do stuff and work with users
Stage 4: Write the code for the front and back parts
Stage 5: Put in all the words and pictures
Stage 6: Check if everything works right
Stage 7: Keep it running smoothly after it's out there
