Overriding props

[ishaiavrahami]

Hello, i'm experiencing a bit unusual belabor. Im currently using Vuex to store my tabs in a small array variable and right after mounting the component i'm noticing that my variable is no long a small array rather a much larger array which seems to be inheriting the props data (which should be readonly). Any idea whose fault is this?

If you are using Vuex, you will need to mirror a copy of the data from above.
