Caution

DevGod needs to write an editorial for this problem!

js

/**
 * @param {string} word
 * @return {boolean}
 */
var detectCapitalUse = function(word) {
    if(word === word.toUpperCase()){
        return true;
    }
    if(word === word.toLowerCase()){
        return true;
    }
    if(word === word[0].toUpperCase()+word.slice(1,word.length).toLowerCase()){
        return true;
    }
    return false;
};
