reactjs - Search in Redux store if specific string exists in messages array

Question

I'm trying to use something like a contains() function in redux but apparently it doesn't exist.

    case types.FILTER_MESSAGES_BY_CONTENT:
        return {
            ...state,
            messageSearchResults: state.messages.map(message => message.content.contains(action.search))
        };

Action:

export function filterMessagesByContent(search) {
    return {
        type: types.FILTER_MESSAGES_BY_CONTENT,
        search: search
    };
}

Console.log of messages returns me this (one of them):

0:
category: "posuere"
comments: (4) [{…}, {…}, {…}, {…}]
content: "Quisque id justo sit amet sapien dignissim vestibulum. Vestibulum ante ipsum primis in faucibus orci luctus et ultrices posuere cubilia Curae; Nulla dapibus dolor vel est. Donec odio justo, sollicitudin ut, suscipit a, feugiat et, eros."

In this case messages has all messages and in messageSearchResults I want to put every message that contains the search query I'm giving.

How would I do this?

Answer 1

I think try this, this should returned the filtered messages

messageSearchResults: state.messages.filter(message => message.content.includes(action.search))

since

"Quisque id justo sit amet".includes("id") // returns true

However, I should point out that includes would work query is container in the message.content.

Answer 2

U can also filter like this and check its include or not.

messageSearchResults: state.messages.filter({content}=>content.includes(action.search));
