how to combine regEx expressions

How do I take each of these and combine them into a single regEx expression?

var t = "<test>";
t = t.replace(/^</, '');
t = t.replace(/>+$/, '');

which results in t equal to test without the <>

If I understand correctly you only want to replace beginning '<' symbols and ending '>' symbols, try this one [>$^<]

var t = "<test>";
t = t.replace('/[>$^<]/', '');

Try this

t = t.replace(/^</, '').replace(/>+$/, '');

If you want it in single line, use | to combine the regex.. Like this

t = t.replace(/^<|>+$/g, "");

or capture groups like this

t = t.replace(/^<(.*)>+$/g, '$1');

You can use pipe |. In regex it means OR:

t = "<test>>".replace(/^<|>+$/g, "");
// "test"

But of course, you can use another ways like:

t = "<test>>".replace(/[<>]/g, "");
// "test"

or even with match:

t = "<test>>".match(/\w+/)[0];
// "test"

Make sure you've added the g-global flag when needed. This flag stands for all occurrences.
