change part of the string with case sensitive

I would like the search a string without case sensitive however change the sub string with original string's case letters.

var mystring = "FiRst Last";
var term = "first";  // it could be "FIRST" or fIRST

var re = new RegExp("^" + term, "i") ;
//option 1
//var t = mystring.replace(re,"<span style='font-weight:bold; color:Blue;'>" + term + "</span>");
//option 2
var t = mystring.replace(re,term.bold().fontcolor("Blue"));

The above code gives first LAST in blue color, however i want it to be FiRst LAST as mystring's case order

maybe indexof() method can be used however there might be an easy efficient way.

var querystr = 'first';
var output = "FiRst Last";
var reg = new RegExp(querystr, 'gi');
var final_str = output.replace(reg, function(str) {return str.bold().fontcolor("Blue")});

Just use a capture group with your first option

var str = "FiRst Last";
var term = "first";

var t = str.replace( /(first)/i, "<span style='font-weight:bold; color:Blue;'>$1</span>");

t will now contain

"<span style='font-weight:bold; color:Blue;'>FiRst</span> Last"
