Randomly shuffling an array of literals in JavaScript
We are required to write a JavaScript function that takes in an array of literals.
Then the function should shuffle the order of elements in any random order inplace.
Example
The code for this will be −
const letters = ['a', 'b', 'c', 'd', 'e', 'f', 'g'];
const unorderArray = arr => {
let i, pos, temp;
for (i = 0; i < 100; i++) {
pos = Math.random() * arr.length | 0;
temp = arr[pos];
arr.splice(pos, 1);
arr.push(temp);
};
}
unorderArray(letters);
console.log(letters);Output
And the output in the console will be −
[ 'b', 'e', 'c', 'a', 'g', 'f', 'd' ]
Note that this is just one of the many possible outputs.
