[BUG] Array index assignment followed by push only assigns

[michaelboyles]

Describe the bug

An array assignment to a specific index, followed by a call to a method such as Array.push will completely ignore the second method, and only the assignment will occur

Sample input

interface NumberArrayState {
    arr: number[]
}
const reducer = redcr((state: NumberArrayState) => {
    state.arr[1] = 123;
    state.arr.push(456);
});

Current output

Specify which ES version you're targeting: ES2020

const reducer = (state) => {
    state = {
        ...state,
        arr: Object.assign([...state.arr], { [1]: 123 })
    };
    return state;
};
