tryor v0.1.2

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.

Usage

    // 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.

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