How can i get array indexOf element includes value Like

var a = ["one","two","xx?ee"]; 

a.indexOf("?"); //i want to get indexOf element xx?ee

Taki :

Use Array.findIndex and String.includes

var a = ["one","two","xx?ee"]; 

var ndx = a.findIndex(e => e.includes("?"));

console.log(ndx);

Keep in mind that this will return the first match only.
