Thanks I found what i was doing wrong here.

Some tests are susceptible to mutation of input arguments and fail if your solution changes input objects passed to it. If the kata does not explicitly ask you to modify input arguments, make sure you do not do it. If you find a kata that fails when input is mutated by your solution, raise it as an issue (see here).

what is this below ?

/workspace/node/test.js:30
