If you are getting the error "js object is not iterable", it means that you are trying to iterate over an object using a loop or a higher-order function that expects an iterable, such as `for...of` loop, `forEach()`, `map()`, or `spread operator (...)`.
In JavaScript, objects are not directly iterable. However, you can iterate over the keys or values of an object using a `for...in` loop or by using `Object.keys()`, `Object.values()`, or `Object.entries()` methods.
Here's an example of how you can iterate over the keys or values of an object:
```javascript
const obj = { key1: 'value1', key2: 'value2', key3: 'value3' };
// Iterate over keys
for (const key in obj) {
console.log(key);
}
// Iterate over values
for (const value of Object.values(obj)) {
console.log(value);
}
// Convert object to array of key-value pairs and iterate
const entries = Object.entries(obj);
for (const [key, value] of entries) {
console.log(key, value);
}
```
Make sure to use the appropriate method or loop based on your specific use case.
