I want to render the number of images and images should be shuffle in react native? how to do that? Can any one help me

Question

Images should be shuffle when i'll click on that particular image in react native.

Answer 1

You can use shuffle of lodash library or can make your shuffle function. I am taking image URLs as a number in the below example.

function shuffle(array) {
  var currentIndex = array.length, temporaryValue, randomIndex;

  // While there remain elements to shuffle...
  while (0 !== currentIndex) {

    // Pick a remaining element...
    randomIndex = Math.floor(Math.random() * currentIndex);
    currentIndex -= 1;

    // And swap it with the current element.
    temporaryValue = array[currentIndex];
    array[currentIndex] = array[randomIndex];
    array[randomIndex] = temporaryValue;
  }

  return array;
}

// Used like so
var arr = [2, 11, 37, 42];
arr = shuffle(arr);
console.log(arr);
