Not allowing me to push object into an array

Question

I\'m working with Angular. I\'m trying to push an object into an array but it giving me errors. It says that TypeError: Cannot read property \'push\' of undefined

Answer 1

So if it worked for you and as I saw at least few similar questions latly. If you have TypeError: Cannot read property 'whatever' of undefined that means you didn't declared some property. This is declaration:

someProperty: SomeType = []

if you have this its only definition:

someProperty: SomeType

and trying do any operation on it will result in above error.
