Convert URL Text Into Clickable HTML Link Using JavaScript

    function Linkify(inputText) {
        //URLs starting with http://, https://, or ftp://
        var replacePattern1 = /(\b(https?|ftp):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/gim;
        var replacedText = inputText.replace(replacePattern1, '<a href="$1" target="_blank">$1</a>');

        //URLs starting with www. (without // before it, or it'd re-link the ones done above)
        var replacePattern2 = /(^|[^\/])(www\.[\S]+(\b|$))/gim;
        var replacedText = replacedText.replace(replacePattern2, '$1<a href="http://$2" target="_blank">$2</a>');

        //Change email addresses to mailto:: links
        var replacePattern3 = /(([a-zA-Z0-9_\-\.]+)@[a-zA-Z_]+?(?:\.[a-zA-Z]{2,6}))+/gim;
        var replacedText = replacedText.replace(replacePattern3, '<a href="mailto:$1">$1</a>');

        return replacedText
    }

Saved me a bunch of time! I added some look behind to make sure I wasn't converting links which were already in an anchor tag,

What if need to remove these parentheses(curve brackets) '(' and ')' from inputext ?

Can add following at the top but what could be the possibility if needed in existing lines ?

    var replacePattern4 = /[()]/g;
    replacedText = inputText.replace(replacePattern4, '');
