Javascript equivalent to python dict(zip(['AB', 'CD', 'EF', 'GH'],[1, 2, 3, 4])) - 2 js arrays to one js object

dict_zip

var keys = ['AB', 'CD', 'EF', 'GH'];
var values = [1, 2, 3, 4];

// Equivalent to python dict(zip(['AB', 'CD', 'EF', 'GH'],[1, 2, 3, 4])) in javascript
function dictZip(key_array, val_array) {
  if (key_array.length === val_array.length) {
    return key_array.reduce((acc, curr, index) => {
      acc[curr] = val_array[index];
      return acc;
    }, {});
  } else {
    console.error("Wrong length");
  }
}

console.log(dictZip(keys, values));

you could just do:

Object.fromEntries(keys.map((e, i) => [e, values[i]]));

Completely right. Never changed the logic in the snippet since 2012 and then 2017 where no Object.fromEntries did not exist.
Method present only since "ES2019"
Thanks for the feedback
