How Can You Find the Position of a Substring in a String?

The third question states

Incorrect.

Remember that the indexOf() method is case sensitive.

Except that the requested word Javascript is capitalized the same as JavaScript in the sentence.

if I found the correct question, the code block is

const str = "I am learning JavaScript.";
str.indexOf("Javascript");

they are not capitalized the same, so indexOf will not find Javascript inside str, because there isn’t, instead there JavaScript which has a different capitalization

the feedback is correct
