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


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.

    // 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.

Install using npm

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