Copywriter

This is one of those skills that pays for itself immediately if you've ever stared at a button wondering whether it should say "Submit" or "Create Account." It walks you through the actual patterns that make UX copy work: specific button labels with verb plus noun, error messages that explain how to fix the problem instead of just saying "invalid input," empty states that guide users instead of leaving them stranded. The landing page section is solid too, with real formulas for hero copy and CTAs that focus on benefits over features. Everything comes with before and after examples in TypeScript and React components, so you can see exactly what good copy looks like in context. It's basically a cheat sheet for writing microcopy that doesn't make users think twice.

UX Writing Patterns

Button Labels

// ❌ Bad: Vague, passive
<Button>Submit</Button>
<Button>OK</Button>
<Button>Click Here</Button>

// ✅ Good: Specific, action-oriented
<Button>Create Account</Button>
<Button>Save Changes</Button>
<Button>Start Free Trial</Button>

Guidelines:

Use verb + noun ("Save Changes" not "Save")
Be specific ("Delete Post" not "Delete")
Show outcome ("Start Free Trial" not "Submit")

Error Messages

// ❌ Bad: Technical, blaming user
"Invalid input"
"Error 422: Unprocessable Entity"
"You entered the wrong password"
