跟据英文解释简单总结下:splice -- 粘贴在一起; split -- 分开几部分; slice -- 切片,切除某一部分。理解这些了,我们就不难理解JS里的这些方法了。 splice -- 用于对数组进行,添加,替换和删除 (不就是把东西粘一起吗,添加--粘新东西,替换--在已有的位置上粘东西,删除--在已有的位置上粘空东西)。 spl...
今天我看了NN4的源码 链接 ,确认确实JS的split是从Perl抄的,而且JS1.2特意补上了一开始Brendan没有来得及抄全的行为,比如支持正则,比如 split(' ') 的特殊行为:trim头尾,然后split(/\s+/)。所以我相信Netscape工程师当时的计划肯定是照抄Perl的。而且我发现MDN当年的文档 New in JavaScript 1.2中对split的变更...

In fact, even the aforementioned MDN page has removed the aforementioned statement abou...
infromEvent(), in this case also removing the need for this operation to beasync. Additionally, this allows bundlers to more effectively tree-shake the module in case the other code is never used. The JSDoc on the function itself has also been improved with additional details for the ...
To split a string by special characters, call the `split()` method on the string, passing it a regular expression that matches the special characters.
here + means to make strings to number,like jsfuck[]()!+; --- from MDN, this static method creates a new, shallow-copied Array instance from an array-like or iterable object. i.e Array.from('foo')===["f","o","o"] Array.from(123...
