Can part of a string be rearranged to form another string in JavaScript
Problem
We are required to write a JavaScript function that takes in two strings, str1 and str2. Our function should return true if a portion of str1 characters can be rearranged to match str2, otherwise returns false.
Example
Following is the code −
const str1 = 'rkqodlw';
const str2 = 'world';
const canForm = (str1 = '', str2 = '') => {
if(str1.length < str2.length){
return false;
};
const res = str2.split('');
str1.split("").forEach(val => {
if(res.includes(val)){
res.splice(res.indexOf(val), 1);
};
});
return res.length === 0;
};
console.log(canForm(str1, str2));Output
Following is the console output −
true
