No, people aren’t using if statements for assignment very commonly at all in JavaScript, not when you have ?, ?., &&, ||, and ?? as options.

And React developers have to significantly rearchitect the JSX in their return statements if they want to replace a ? (or &&) for conditional rendering with guard clauses (if x return <>X</>).

Of course, if (and, for some developers, else) are commonly used for branching code — executing different statements based on certain conditions being met. But they’re not common with = assignment.
