前端做字符串拼接,大概拼接到5亿多长度时就报一个 Uncaught RangeError: Invalid string length 错误,不管是用…JS字符串的长度受到下标限制。理论最大长度是2^53-1(即js中可表达的最大安全整数)。2^53是多大呢?大约9PB。根据统计,中国2014年所有出版物(不计复本)不到2000亿

注意: 对于上面——strings--line-length,长字符串不受此规则限制,不应分解。 eslint: max-len jscs: maximumLineLength Why? 这样确保可读性和可维护性 // bad const foo = jsonData && jsonData.foo && jsonData.foo.bar && jsonData.foo.bar.baz && jsonData.foo.bar.baz.quux && jsonData.foo....
It is always a good idea to use objects with a smaller string length where possible. This way, your obfuscated code will be easier to produce and will require fewer characters. Again, the same technique is used to obtain 2. We simply wrap another array, and access the first element and ...

const resArr = regVal.exec(currencyTempString); if (resArr) { maxFractionDigits = resArr?.[1]?.length; } 方式二: 第一个数字输入数字0, 转换后的'货币字符串'比如 '$0.00' 或者'0.00₫', 第二个数字输入0但同时指定保留小数0位, 然后将两个字符串长度相减后再减一, 限制这...
