Short description

Keep filters pure/fast — they may run often during digests.

Custom filter

angular.module('myApp').filter('truncate', function () {
  return function (value, limit) {
    limit = limit || 20;
    value = value || '';
    return value.length > limit ? value.slice(0, limit) + '…' : value;
  };
});
