javascript - 匹配空格分隔的固定字符组

Question

例如，我需要匹配3组字符，每个字符以空格分隔，在此文本上:

This is also true for humans, who can (...) hear only a limited range [12^] of sounds as well. Dogs, dolphins and other creatures can hear different frequencies than we do, for example. There is some scientific evidence our brains are receiving a much wider range of frequencies than we are able to perceive. Michael Weliky from the University of Rochester conducted a study which led him to conclude that perhaps as much as 80% of the frequencies we receive are locked in our heads, unable to be perceived.

我发现这个语法给了我我想要的结果:
[^].+?(?=).+?(?=).+?(?=)

但我想知道它是否可以改进，看起来它看起来很多余。

Answer 1

您可以删除中间的两个前瞻并仅替换为空格。

[^].+？ .+？ .+?(?= ) example

除此之外，您可能无法进行匹配。
