@ngdoc error
@name $parse:isecaf
@fullName Assigning to Fields of Disallowed Context
@description

Occurs when an expression attempts to assign a value on a field of any of the `Boolean`, `Number`,
`String`, `Array`, `Object`, or `Function` constructors or the corresponding prototypes.

Angular bans the modification of these constructors or their prototypes from within expressions,
since it is a known way to modify the behaviour of existing functions/operations.

To resolve this error, avoid assigning to fields of constructors or their prototypes in expressions.
