import { A, B, C } from 'lib'
// After
import { A, C } from 'lib' // B was unused
Add Type Annotations
// Before

function process(data: DataItem[]): number[] {
return data.map(x => x.value)
}
Fix Missing Keys
// Before
{items.map(item => <div>{item.name}</div>)}
// After
{items.map(item => <div key={item.id}>{item.name}</div>)}
Focus on fixes that improve code quality and prevent bugs. Run linting before every commit.
