So I came across this question.....

#coding #javascript #interview

Given two strings, return true if they are one edit away from each other, else return false.

and this is my solution but I cannot get my answer:

//code:

const isobj = (str) => {
let obj = {};

for (const char of str) { !obj[char] ? (obj[char] = 1) : obj[char]++; } return obj;
Enter fullscreen mode Exit fullscreen mode

};

const isedit = (str1, str2) => {
let obj1 = isobj(str1);
let obj2 = isobj(str2);

// console.log(obj1,obj2) let counter = 0; for (let key in obj2) { if (obj1[key] == obj2[key]) { continue; } else { if (obj1[key] - obj2[key] == 1) { counter++; } else { return false; } } } console.log(counter); if (counter == 1) { return true; } else { return false; }
Enter fullscreen mode Exit fullscreen mode

}

console.log(isedit("pal", "pale"));
