<div class="desc"><p>Returns <code>sqrt(x*x + y*y)</code> — the length of the 2D vector <code>(x, y)</code>, or equivalently the hypotenuse of a right triangle with those legs. It is the one-call form for a magnitude and reads more clearly than spelling out the squares and root. To normalize a vector, divide each component by its <code>Math.hypot</code>.</p></div>
