arty

tiny javascript library for asserting types on function arguments

To use:

t = require('arty');

var add = function (n1, n2) {
  return n1 + n2;
};

console.log(add(3, 4));
=> 7
console.log(add(3, {}))
=> 3[object Object]


var typed_add = t('number', 'number')(function (n1, n2) {
  return n1 + n2;
});


var typed_subtract = t('number', 'number'); /* function declaration */

var typed_subtract(function (n1, n2) { /* function definition */
  return n1 - n2;
});


var times = function (n1, n2) { return n1 * n2; };
var typed_times = t('number', 'number')(multiplication);

To test:

npm install
mocha --compilers coffee:coffee-script/register
