JavaScript How can I replace the value in an array using redux? replace value array javascript,replace value array php,replace value

I'm trying to overwrite a specific value in my Redux state which is an array. I have gotten the index already and also the value of the new text. I'm just not sure about the best way of overwriting the previous text. Here is my reducer so far. The UPDATE_LINK is the one I'm having trouble with.

export function linkList(state = [], action) {
    switch(action.type) {
        case 'ADD_LINK': 
            var text = action.text;
            console.log('Adding link');
            console.log(text);
            return {
                ...state,
                links: [text, ...state.links]
            };
        case 'DELETE_LINK':
            var index = action.index;
            console.log('Deleting link');
            return {
                ...state,
                links: [
                    ...state.links.slice(0, index),
                    ...state.links.slice(index + 1)
                ],
            };
        case 'UPDATE_LINK':
            var index = action.index;
            var newText = action.newText;
            console.log(action.newText);
            console.log(action.index);
            return {
                ...state,
                // How do I update text? 
            }
        default: 
            return state;
    }
};

export default linkList;
