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

    var config = tryor(function() {
        return JSON.parse(String(fs.readFileSync("config.json")));
    }, {});

    // instead of
    var config = {};
    try {
        config = JSON.parse(String(fs.readFileSync("config.json")));
    } catch (e) {
    }

Works extra well with ES6-style const variables.
