I have an array of objects, and I'd like to randomize the order of the elements.

So I have the following:

const animals  = data?.fetchAllAnimals;
let randomizeAnimals = animals.sort(()=> Math.random() -0.5 )

But I keep getting this error in firefox: TypeError: 0 is read-only

and a different error in chrome: TypeError: Cannot assign to read only property '0' of object '[object Array]'

What am I doing wrong here?

  • It seems that the array has been frozen (or something similar) so that it cannot be changed. So enzou's solution should work. Commented Mar 9, 2022 at 19:14
  • Yes that worked! I just did let randomizedAnimals = [...animals]; randomizedAnimals.sort(() => Math.random() - 0.5); and everything is working okay now Commented Mar 9, 2022 at 20:33
