What you are looking for are called regular expressions. For more information, you can visit a site like: http://www.regular-expressions.info/

Note that regular expressions are not specific to JavaScript.

For your specific example:

string.replace(/abc.+xyz/,"abc"+newString+"xyz");

. means any character, and + means one or more occurences.

If you have more than one replacement to do, try:

string.replace(/abc.+?xyz/g,"abc"+newString+"xyz");

g stands for general, and ? is the lazy quantifier, meaning that it will stop at the next occurence of xyz in the string.
