Splitting Strings You can split a string based on a regex pattern using thesplit()function import{RE2JS}from're2js'RE2JS.compile('/').split('abcde')// ['abcde']RE2JS.compile('/').split('a/b/cc//d/e//')// ['a', 'b', 'cc', '', 'd', 'e']RE2JS.compile(':').sp...
⽅法1：const replaceStr1 = (str, index, char) => { const strAry = str.split('');strAry[index] = char;return strAry.join('');} replaceStr(str1, 4, '-'); // => Good-Morning replaceStr(str2, 4, '-'); // => Hell- World js的字符串有个substring⽅法，⽤于提取字符...
