ValueError

ValueError, an instance of Error, for Node.js

Installation

npm install valueerror

Usage

Same as the Error constructor function. For example,

var ValueError = require('valueerror');
...
throw new ValueError('Input cannot have underscores');

The new is optional here. So the above code can be written as

throw ValueError('Input cannot have underscores');

Similarly, the ValueError can be used to check the instance like this

new ValueError() instanceof ValueError // true
new ValueError() instanceof Error      // true
