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");
