Checks if a string is an anagram of another string (case-insensitive, ignores spaces, punctuation and special characters).
Use String.prototype.toLowerCase()
, String.prototype.replace()
with an appropriate regular expression to remove unnecessary characters, String.prototype.split('')
, Array.prototype.sort()
and Array.prototype.join('')
on both strings to normalize them, then check if their normalized forms are equal.
代码片段
const isAnagram = (str1, str2) => {
const normalize = str =>
str
.toLowerCase()
.replace(/[^a-z0-9]/gi, '')
.split('')
.sort()
.join('');
return normalize(str1) === normalize(str2);
};
使用样例
isAnagram('iceman', 'cinema'); // true
