Basic Data Structures: Create complex multi-dimensional arrays question

JavaScript
1

Hello. This is my code:

let myNestedArray = [
  // change code below this line
  ['unshift', false, 1, 2, 3, 'complex', 'nested',
    [ 'deep'
       [ 'deeper'
         [ 
           'deepest'
         ]
       ]
    ]],
  ['loop', 'shift', 6, 7, 1000, 'method'],
  ['concat', false, true, 'spread', 'array'],
  ['mutate', 1327.98, 'splice', 'slice', 'push'],
  ['iterate', 1.3849, 7, '8.4876', 'arbitrary', 'depth']
  // change code above this line
];

I don’t get what is wrong with it. Any ideas?
