What it does

The proposal-change-array-by-copy tool provides additional methods on Array.prototype and TypedArray.prototype to enable changes on the array by returning a new copy of it with the change, allowing for immutable array modifications.

When to use it

•When working with immutable data structures and needing to modify arrays without changing the original
•When requiring a more functional programming approach to array modifications
•When needing to track changes or maintain a history of array modifications

Ready-to-paste prompt

Try the following example: `let arr = [1, 2, 3]; let newArr = arr.addTo(1, 4); console.log(newArr); // [1, 2, 3, 4]`

Heads up: Note that this proposal is not yet fully implemented in all JavaScript environments and may require a specific version of Node.js or a transpiler like Babel to work correctly
