split camelcase string into array of words words - Page 2

pantagruel

Hi,

I'm looking for an optimal javascript function to split a camelcase
string and return an array.

I suppose one could loop through the string, check if character is
uppercase and start building a new word to add to the array but that
seems incredibly wasteful. must be some easy way to do it.
Thanks.

But this : "camelCaseStrin g".match(/(\b|[A-Z])[a-z]*/g)
returns ['camel','Case', 'String']

And this : "camelCaseSTRin g".match(/(\b|[A-Z]+)[a-z]*/g)
returns ['camel','Case', 'STRing']

What does \b do? Never seen that before.

\b Matches a word boundary, that is, the position between a word and a
space. For example, 'er\b' matches the 'er' in "never" but not the 'er'
in "verb".

\b Matches a word boundary, such as a space. (Not to be confused with
[\b].) For example, /\bn\w/ matches the 'no' in "noonday";/\wy\b/
matches the 'ly' in "possibly yesterday."
Note that the documentations quoted above are inadequate, not really
defining "word boundary".

A Web search should find lists of RegExp parts.

<FAQENTRYRegExp s are often asked about, but the FAQ is little help
(two links in 4.16); AFAIK, the Notes do not cover them (IMHO, the FAQ
should have a link to EACH of the Motes).
