Finding and returning uncommon characters between two strings in JavaScript
Problem
We are required to write a JavaScript function that takes in two strings. Our function should return a new string of characters which is not common to both the strings.
Example
Following is the code −
const str1 = "xyab";
const str2 = "xzca";
const findUncommon = (str1 = '', str2 = '') => {
const res = [];
for (let i = 0; i < str1.length; i++){
if (!(str2.includes(str1[i]))){
res.push(str1[i])
}
}
for (let i = 0; i < str2.length; i++){
if (!(str1.includes(str2[i]))){
res.push(str2[i])
}
}
return res.join("");
};
console.log(findUncommon(str1, str2));Output
