tryor.js

Give it a function and a default value. tryor will give you back the return value of the function or, in case the function threw an exception, the default value. Works in node and browsers.

Usage

javascript
    // do this
    var config = tryor(function() {
        return JSON.parse(userProvidedConfigString);
    }, {});

    // instead of
    var config; // or var config = {}; and empty catch
    try {
        config = JSON.parse(userProvidedConfigString);
    } catch (e) {
        config = {};
    }

Works extra well with ES6-style const variables.
