Passing parameters to a callback function using arrow function

rated 0 times [ 15] [ 3] / answers: 1 / hits: 47478 / 6 Years ago, thu, july 5, 2018, 12:00:00

I know this is a duplicated question with ES5, but I am looking for the syntax with ES6 arrow function. My code below:

fetchItems = (callback) => {

    //After ajax success

    callback(response);

}



const myParams = {name:John}

this.fetchItems((res) => {

    console.log(res.data);

});

For the above scenario, I want to pass some parameters(myParams) along with the function call, how can I achieve that?

You can do that:

const fetchItems = (callback, ...params) => {

    //Do whatever you want with the params

    callback(response);

}

Example of usage:

const fetchItems = (callback, ...params) => {

    callback(params);

}

    

fetchItems (console.log, 'foo', 1);
