Then we turned enlightened to raised practices, separating HTML from CSS and JavaScript. Then got here React and JSX, the place we mix JavaScript, HTML, and even CSS with Styled Parts — what a sublime mess we have made!

Each from time to time a part of that mess is me seeing 0 displaying within the output of my JSX code, and I am reminded why: improper dealing with of variable typing, mixed with utilizing &&. Let me clarify!
