A quick review
- Functionality, as @Mast stated, this should be at least integrated with localStorage so that the data survives closing the browser
- Practices, Avoid
console.log, at least wrap it with some debug mode checking functionality - Design, having
'todo''todo','in progress''in progress', and'done''done' as hardcoded arrays, functions, and indexes is a super inflexible design. I don't know what the right React.js approach is to have these items appear in the correct column, but this isn't it - Spelling,
advancveTo->advanceTo - CSS,
font-style: favorit;is not valid CSS
