Regex to split camel case

Question

I have a regular expression in JavaScript to split my camel case string at the upper-case letters using the following code (which I subsequently got from here):

Answer 1

Sometime camelCase strings include abbreviations, for example:

PDFSplitAndMergeSamples
PDFExtractorSDKSamples
PDFRendererSDKSamples
BarcodeReaderSDKSamples

And in this case the following function will work, it splits the string leaving abbreviations as separate strings:

function SplitCamelCaseWithAbbreviations(s){
   return s.split(/([A-Z][a-z]+)/).filter(function(e){return e});
}

Example:

function SplitCamelCaseWithAbbreviations(s){
   return s.split(/([A-Z][a-z]+)/).filter(function(e){return e});
}

console.log(SplitCamelCaseWithAbbreviations('PDFSplitAndMergeSamples'));
console.log(SplitCamelCaseWithAbbreviations('PDFExtractorSDKSamples'));
console.log(SplitCamelCaseWithAbbreviations('PDFRendererSDKSamples'));
console.log(SplitCamelCaseWithAbbreviations('BarcodeReaderSDKSamples'));
