What is the preset value for the payload in a vuex action?

Currently, I am utilizing an if-else statement in my Vuex action to set a default value for a payload property. Specifically, I check if the passed payload object contains a delay property; if it does not, I assign it a default value and handle appropriately.

Is there a more concise approach to achieving this task? I believe there must be a better way.

Below is the code snippet of my action:

showModal ( {commit}, modalPayload ) {

        let delay;

        if(modalPayload.delay == undefined) {
            delay = 3000;
        } else {
            delay = modalPayload.delay;
        }

        commit('SHOW_MODAL', modalPayload);
        setTimeout(function(){
            commit('HIDE_MODAL');
        }, delay);

    },

Your suggestions are greatly appreciated. Thank you.

To assign a default value, one can use destructuring assignment as follows:

showModal ({ commit }, modalPayload) {
  const { delay = 3000 } = modalPayload

  commit('SHOW_MODAL', modalPayload);
  setTimeout(() => commit('HIDE_MODAL'), delay);

}

If you do not require passing the delay to the commit function, you can destructure it from the second parameter like this:

showModal ({ commit }, { delay = 3000, ...modalPayload }) {
  commit('SHOW_MODAL', modalPayload);
  setTimeout(() => commit('HIDE_MODAL'), delay);
}
