alternatives are: <pre class='brush: javascript'>var secondIndex = (t, s, p) => 0 > (p = t.indexOf(s)) || 0 > (p = t.indexOf(s, p + 1)) ? [][0] : p </pre> or <pre class='brush: javascript'>var secondIndex = (h, n) => (h = h.match(n+'.*?'+n)) ? h.index+h[0].length-1 : [][0] </pre> or <pre class='brush: javascript'>var secondIndex = (t, s) => [...t.matchAll(s),'',''][1].index; </pre>

:) It is genius. But what does a linter say about it? It is a case when ```=``` is right instead ```==``` or even ```===``` in conditional structures.
