Favor inline conditional rendering in JSX over extracting logic to variables before the return statement, as it maintains better flow control visibility and reduces cognitive overhead when reading components. Additionally, use descriptive variable names that clearly convey their purpose and state.

For conditional rendering, prefer:

return (
  <div>
    {state.specs.length < 1 
      ? <NoSpec />
      : <SpecList />
    }
  </div>
)

Over extracting to variables:

const specListContent = state.specs.length < 1 
  ? <NoSpec />
  : <SpecList />

return (
  <div>
    {specListContent}
  </div>
)

The inline approach keeps the rendering logic visible in context, making it easier to understand what gets rendered without jumping between variable definitions. For variable naming, choose names that clearly indicate the variable’s role - for example, use isRunning instead of isLive when the variable represents whether a process is currently executing.
