Javascript - sort array based on another array

Question

Is it possible to sort and rearrange an array that looks like this:

itemsArray = [ 
    [\'Anne\', \'a\'],
    [\'Bob\', \'b\'],
    [\'Henry\', \'b\'],
             


        

Answer 1

This is what I was looking for and I did for sorting an Array of Arrays based on another Array:

It's On^3 and might not be the best practice(ES6)

function sortArray(arr, arr1){
      return arr.map(item => {
        let a = [];
        for(let i=0; i< arr1.length; i++){
          for (const el of item) {
            if(el == arr1[i]){
              a.push(el);
            }   
            }
          }
          return a;
      });
    }
    
    const arr1 = ['fname', 'city', 'name'];
  const arr = [['fname', 'city', 'name'],
  ['fname', 'city', 'name', 'name', 'city','fname']];
  console.log(sortArray(arr,arr1));
