DANGER: will not check if the name is redefined in scope. An example case here, for instance var q = Math.floor(a/b). If variable q is not used elsewhere, UglifyJS will drop it, but will still keep the Math.floor(a/b), not knowing what it does. You can pass pure_funcs: [ ...

The isTitle method returns True if all words in a text start with a upper case letter, AND the rest of the word are lower case letters, otherwise False.// The isTitle method are used for check the // given string in title form or not. console.log(solverjs.isTitle('Title')); // ...
console.log( string.match(regex) ); // => ["abbc", "abbbc", "abbbbc", "abbbbbc"] 注意:案例中用的正则是/ab{2,5}c/g,后面多了g,它是正则的一个修饰符。表示全局匹配,即在目标字符串中按顺序找到满足匹配模式的所有子串,强调的是“所有”,而不只是“第一个”。g是单词global的首字母。
