# 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
|
||
|
|
```javascript
|
||
|
|
// 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.
