How to loop through JSON with Node.js?

Spread the love

To loop through JSON with Node.js, we use the forEach method.

For instance, we write

const objectKeysArray = Object.keys(yourJsonObj);

objectKeysArray.forEach((objKey) => {
  const objValue = yourJsonObj[objKey];
});

to call Object.keys to get the object’s keys in an array.

Then we call forEach with a callback to get the property value with yourJsonObj[objKey].
