How to use JavaScript foreach loop on an associative array object?

Spread the love

To use JavaScript foreach loop on an associative array object, we use the Object.entries method.

For instance, we write

const h = {
  a: 1,
  b: 2,
};

Object.entries(h).forEach(([key, value]) => console.log(value));

to call Object.entries with h to return a key-value pair array.

Then we call forEach with a callback that destructures the key and value from the array.

And we log the property value of each entry.
