About unloading modules

[anhldbk]

Would you please tell me what will happen with the unloaded module?

In the following image, I expected variable lodash will be undefined or null after the associated module is unloaded. But it's not.

That won't happen, because you are holding a reference in your lodash variable. .unload('lodash') will remove the module and its dependencies from require.cache. So the next time you do var lodash2 = require('lodash') it will be different from lodash != lodash2.
