Write a JavaScript program that checks if two strings are anagrams of each other.
Code:
function checkIfAnagrams(str1, str2) {
const formatStr = str => str.replace(/[^\w]/g, '').toLowerCase().split('').sort().join('');
return formatStr(str1) === formatStr(str2);
}
var result = checkIfAnagrams('Listen', 'Silent');
console.log(result);
