javascript string data-structures logic 在这里,我创建了一个字符串压缩程序,因此对于输入字符=[“a”,“a”、“b”,“b”、“c”,“c”],我们得到的输出像6个字符[“a,”2“,”b“,”2”,“c”,“3”]。因此,我使用数组方法创建了一个程序,它也非常冗长和复杂。有没有什么解决方案可以使用two-poin...
push(String.fromCodePoint(bytes[i])); i += 1; break; case 2: chars.push(String.fromCodePoint( (bytes[i] & 0x1F) << 6 | (bytes[i + 1] & 0x3F) )); i += 2; break; case 3: chars.push(String.fromCodePoint( (bytes[i] & 0x0F) << 12 | (bytes[i + 1] & 0x3F) ...

stdinbytes():读取标准输入的内容,返回Uint8Array; 字符串操作 format(template, ...args):格式化字符串,如format("a=%d, b=%s", 123, "xxx"); randomstring(size, chars?):生成随机字符串; formatdate(format, timestamp?):格式化日期时间,格式参考PHP的date()函数,文档参考https://locutus.io/php/datet...
This could be thought of as "less strict" parsing. To make it "more strict", one could pass extract: false flag, in which case the function will attempt to parse the input string as if the whole string was a phone number. Applied to the example above, it would return undefined ...
randomstring(size, chars?):生成随机字符串; formatdate(format, timestamp?):格式化日期时间,格式参考PHP的 date() 函数,文档参考https://locutus.io/php/datetime/date/; deepmerge(target, src):深度合并两个对象; 编码解码操作 base64encode(data):Base64 编码字符串; ...
