tryor

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.

Similar packages

Other packages similar to tryor

try-catch

The try-catch package provides a similar functionality to tryor by allowing you to execute a function and catch any errors that occur. However, try-catch focuses more on providing a try-catch block as a function, whereas tryor is more about returning a default value in case of an error.

safe-eval

The safe-eval package allows you to safely evaluate JavaScript code without risking security issues. While it is not exactly the same as tryor, it provides a way to handle potentially unsafe operations in a controlled manner. It is more focused on evaluating code safely rather than handling errors and returning default values.

promise-try

The promise-try package is designed to handle promises and asynchronous functions in a way that catches errors and allows for default values or fallback operations. It is similar to tryor in that it provides a way to handle errors gracefully, but it is more focused on promises and async/await patterns.
