let arr = [1, 2, 3];
arr.push(4, 5);
```

console.log(arr); // Output: [1, 2, 3, 4, 5]

	const flattenObject = (input, keyName) => {
	var result = {};
	for (const key in input) {
	const newKey = keyName ? `${keyName}_${key}` : key;
	if (typeof input[key] === "object" && !Array.isArray(input[key])) {
	result = {...result, ...flattenObject(input[key], newKey)}
	} else {
	result[newKey] = input[key];
	}
	}
