title: Does deep nesting flexbox layout cause performance issue?
body: <p>I have been working on a ReactJS project where I create most of the components using flexbox layout. Since with react, we can have deeply nested components, so my layout is having nested flexbox layout. </p>
  
  <p>Now my question is, does this have any issue with performance? On a single page, there are many components and each component have 3 to 4 level nested flexbox layout. Will that cause a performance issue?</p>
