Tell us what’s happening:
str.indexOf(re));//why it is not giving other number than -1
i changed str also to before, word, also added some words with capitals but gives just -1;
Your code so far
//str = str.replace(before, after);
var str2 = str.split(" ");
var a = str2.indexOf(before);
var word = str2.splice(a,1);
var re = /[A-Z]/g;
//console.log(before.indexOf(re));
//document.write(str.indexOf(re));//why it is not giving other number than -1; it should check Capital letter
if(word.indexOf(re) === -1) {
str2.splice(a, 0,after);
return str2.join(" ");
}else {
var capitalLetter = after[0];
var newWord = capitalLetter.toUpperCase();
return newWord;
}
//document.write(str2);
}
//myReplace("A quick brown fox jumped over the lazy dog", "jumped", "leaped");
myReplace("He is Sleeping on the couch", "Sleeping", "sitting");
