Problem

I would like when I make "asdhusaidhi asdhasuidhu".indexOf('s') it would return 17 referring to the last s of the string, for example, it start looking for the right ..

but instead it returned me 1 for the first s

found

Question?

How can I get him to start searching right?

You can use .lastIndexOf () that returns the last index where this string 's' was found. 

"asdhusaidhi asdhasuidhu".lastIndexOf('s'); // 17

The function you want is lastIndexOf() 

document.body.innerHTML += "asdhusaidhi asdhasuidhu".lastIndexOf('s');
