tryor

return fn() or default value (in case of exception)

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.

    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.

Install using npm

npm install tryor
var tryor = require("tryor");
