A simple utility that helps throw exceptions.
npm install throwYou can't use throw statement in expressions in JavaScript:
``js`
arg = arg || throw new Error('arg is required');
// => SyntaxError: Unexpected token throw
This tiny library is wrapping throw in a function:
`js
var thr = require('throw');
// ...
arg = arg || thr('arg is required');
`
Messages can contain printf-like placeholders:
`js`
arg = arg || thr('"%s" is required', argName);
You can specify instance of Error instead of message:
`js`
arg = arg || thr(new Error('arg is required'));
Or parametrize error class:
`js`
arg = arg || thr(Error, 'arg is required');
`bash`
$ npm install --save throw
`js
var thr = require('throw');
var parsed = parse(str) || thr('Could not parse "%s"', str);
