Here is what I want:
I have first array and I have the index as below:
const first = ['a','b','c'];
const index = 1; // the index of b
const shuffled = ['c','a','b']; // now the index of b is 2
In the first array the index points to the second element in the array which is b right?
Now I shuffled the first array and we have the shuffled array .
The index of b is 2 right now. I want to return this new index...
Using Array#indexOf:
const first = ['a','b','c'];
const index = 1;
const shuffled = ['c','a','b'];
const target = first[index];
const newIndex = shuffled.indexOf(target);
console.log(newIndex);You can use,
Let value = first[index]
let newValue =shuffled.indexof(value)
you can use shuffled.indexOf(first[index])
first[index] returns the value of the first index in this case 'b'
shuffled.indexOf('b') would return the index of b in the shuffled array
