JS: How to find double question mark in string

Question

E.g. I have sample string as below:

var str = "Visit ? W3Schools ??"

I want to find the double question mark "??" exist in that string.

Anyone can help will be appreciated.

Do you mean you want to extract it? Or just know if it exists in the string? — StudioTime, Sep 11 '18 at 08:39

Use indexOf('??'):

var str = "Visit ? W3Schools ??";
console.log(str.indexOf('??'));

NOTE that if you use includes() it will not work in IE browser.
