Split string into sentences in javascript

Question

Currently i am working on an application that splits a long column into short ones. For that i split the entire text into words, but at the moment my regex splits numbers to

You're safer using lookahead to make sure what follows after the dot is not a digit.

var str ="This is a long string with some numbers [125.000,55 and 140.000] and an end. This is another sentence."

var sentences = str.replace(/\.(?!\d)/g,'.|');
console.log(sentences);

If you want to be even safer you could check if what is behind is a digit as well, but since JS doesn't support lookbehind, you need to capture the previous character and use it in the replace string.

var str ="This is another sentence.1 is a good number"

var sentences = str.replace(/\.(?!\d)|([^\d])\.(?=\d)/g,'$1.|');
console.log(sentences);

An even simpler solution is to escape the dots inside numbers (replace them with $$$$ for example), do the split and afterwards unescape the dots.
