lib/commands/utils/traverse-json.js
function traverseJson(json, callback) {
  let { translations } = json;

  Object.keys(translations).forEach((namespace) => {
    Object.keys(translations[namespace]).forEach((k) => {
      callback(translations[namespace][k], translations[namespace], k);
    });
  });
}
function traverseJson(json, callback) {
  let { translations } = json;

  Object.keys(translations).forEach((namespace) => {
    Object.keys(translations[namespace]).forEach((k) => {
      callback(translations[namespace][k], translations[namespace], k);
    });
  });
}
This will traverse an l10n-JSON file, and call the callback function for each translation item.

For example:

```js
traverseJson(json, (item) => delete item.comment);
```

@method traverseJson
@param {Object} json
@param {Function} callback
