How to read the value from an object in an array?

Question

hey everyone, 

 

I have an array where i can't read the values from it.

 

i have:

const interfaces: string = this.transformArray(product.interfaces);

to see the values i use:

console.log(product.interfaces)
console.log(interfaces)

and the console output is for product.interfaces:

[
  {
    amount: null,
    interface: [ [Object] ],
    __typename: 'interfaces_interface_BlockType'
  },
  {
    amount: null,
    interface: [ [Object] ],
    __typename: 'interfaces_interface_BlockType'
  },
  {
    amount: null,
    interface: [ [Object] ],
    __typename: 'interfaces_interface_BlockType'
  },
  {
    amount: null,
    interface: [ [Object] ],
    __typename: 'interfaces_interface_BlockType'
  }
]

and for interfaces:

undefined, undefined, undefined, undefined

 The true value of this array should be sth like "Digital inputs and outputs (24 VDC level)". i guess i have to take the object from the array and read the object but its just guessing...

Can anyone help me pls?
