Answer 1

You may use

var str = "_Lorem Ipsum_ is simply dummy text";
var t2 = str.replace(/_([^_]*)_/g, '<i>$1</i>');  
console.log(t2);

Details

• _ - matches an underscore
• ([^_]*) - Group 1: zero or more chars other than _
• _ - an underscore.

The replacement contains a replacement backreference, $1, that inserts the Group 1 value in between <i> and </i>.

See the regex demo.
