While immersed in a personal project, I encountered an issue within my code. After some debugging, I managed to identify the problem and implement a workaround solution. However, the original issue remains unresolved.
Take a look at this code snippet:
interface Animals {
id: number;
name: string;
color: string;
}
// More TypeScript code here...

Upon analysis, two major problems surfaced:
Surprisingly, both arrays get modified despite the fact that "filter()" is not supposed to alter the original array according to JavaScript documentation.
Additionally, both arrays undergo modification before the filter function call, which seems counterintuitive.
The proposed workaround involves transforming "zoobis" into an Animal[] instead of retaining the entire Zoo object. This adjustment appears to resolve the issues encountered.
Am I overlooking a fundamental concept in JavaScript or am I committing errors that lead to unexpected outcomes in my code execution?
