错误信息 "typeerror: array.split is not a function" 表明 array.split 被调用了,但 array 并不是一个字符串,而是一个数组。在JavaScript中,.split() 方法是字符串的方法,用于将字符串分割成子字符串数组,而数组没有这个方法,因此会抛出TypeError。 2. 检查 watcher 的实现 我们需要检查 Vue 组件中 watcher ...

Note that if there is a double space between the words in the string, this will be evaluated as a split, although with nothing in it. This may not be the result that you want to see.You can fix this problem by using the Replace function to replace any double spaces with a single ...
Distributing agpuArrayamong workers in a parallel pool using thedistributedorcodistributedfunctions is not supported. If you have multiple GPUs and each worker in your parallel pool has access to a unique GPU, you can instead manually split or initially generate your data as multiplegpuArrayobjects...

console.log((a.toString()+','+b.toString()).split(',').map(function(data){return+data;})); 500个字符和1000个字符长度concat和字符串转换+拼接+转换耗时差异不大,手动谷歌浏览器30-40ms的脚本时间, 超过这个问题直接看字符串数组拼接,人家说当字符串个数较少(少于1000个),或者从固定字符串数组中取...
str.split('').reduce((result, currentChar) =>{result[currentChar] ? result[currentChar] ++ : result[currentChar] =1;returnresult;}, {}) 因为字符类型可以用作对象的键,所以我们这里不使用 Map。 4、多个数组的展平 functionFlat(arr...

multiply(a, b), a * b -- 除法,除法的结果类型都是浮点数,如果除数是0,则结果是 ‘inf’, ‘-inf’, or ‘nan’。 divide(a, b), a / b -- 整除,如果结果是正数,则向下取整;如果结果是负数,则向上取整;如果除数是0,则抛异常。 intDiv(a, b) ...
