<script src="https://cdnjs.cloudflare.com/ajax/libs/react-dom/16.13.1/umd/react-dom.production.min.js"></script>
<div id="root"></div>

Script Preparation code:

function ComponentWithInlineTernary() {
  	const bool = true;
  	const value1 = 1;
  	const value2 = 2;
	const stas = bool ? value1 : value2;
    return React.createElement('button', {}, stas);
}

function ComponentWithUseMemo() {
  	const bool = true;
  	const value1 = 1;
  	const value2 = 2;
	const stas = React.useMemo(() => {
	  return bool ? value1 : value2;
    }, []);
    return React.createElement('button', {}, stas);
}

Tests:

ternary
ReactDOM.render(React.createElement(ComponentWithInlineTernary), document.getElementById('root'))
usememo
ReactDOM.render(React.createElement(ComponentWithUseMemo), document.getElementById('root'))
