`
let text = ‘hello world’,
missingText = ‘helo word’;// Here is a “l”;

function theMissingText () {

return missingLetter;

}

// If it has no missing character, it returns -1

// How to return this character in any variable, regardless of where it is in the text, Example:


let $_text = "original text",
    $_missingText = 'original ext'; // here is "t"

// & here is 

let $_text_2 = "original text",
    $_missingText_2 = 'orignal text'; // here is "i";
