Deprecation Guide for No A With Array Like

Deprecates calling A() when an EmberData ArrayLike class is detected. This deprecation may not always trigger due to complexities in ember-source versions and the use (or disabling) of prototype extensions.

To fix, use the native JavaScript array methods instead of the EmberArray methods and refrain from wrapping the array in A().

Note that some computed property macros may themselves utilize A(), in which scenario the computed properties need to be upgraded to Ember Octane syntax.

For instance, instead of:

A([]);

Use:

[];
