Is there a way to add try-catch to every function in Javascript?

Question

For error reporting, I would like to insert a try-catch wrapper around the code of every function I have.

So basically I want to replace

function foo(ar

I wonder (this is pure speculation, so not sure if this would work) you could do something like this:

function callTryCatch(functionSignature) {
    try {
        eval(functionSignature);
    } catch (e) {
        customErrorHandler(e);
    }
}

function entryPoint() {
    callTryCatch(function() {
        // do function logic
    });
}

Again, this is pure speculation and I haven't tested but if it's even possible I think the key lies in the eval statement.
