for detecting hastags you use regular expeession

hashtagsRegex = /(?<=[\s>])#(\d*[A-Za-z_]+\d*)\b(?!;)/g,

but Safari doesn't support lookbehind yet (that is, your (?<=[\s>]))

Although I can't remember where I found this regular expression, I must have found it on a specialized forum topic, blog post or similar project, providing some guarantee that it would always work the same way Instagram does and never trigger false positives.

If you shall come up with a viable replacement providing support for Safari web browser while preserving that guarantee, I will change it.

Thanks.

Since the Instagram front-end itself transforms hashtags into links, I'll try to find out if they're either using a regular expression on their front-end, or computing it in the back-end and providing the result through their API.

In any case, I'll try to use replace my own implementation by theirs.
