How can I compare the usage of lodash's foreach to the native JavaScript foreach loop?

// plain

Lodash's _.forEach() and native JavaScript's forEach() are both methods used to iterate through arrays.

The main difference between the two is that Lodash's _.forEach() method is faster and more efficient than the native forEach() method.

For example:

// Native forEach()
const arr = [1,2,3];
arr.forEach(el => console.log(el));
// Output: 1 2 3

// Lodash _.forEach()
const arr = [1,2,3];
_.forEach(arr, el => console.log(el));
// Output: 1 2 3

The code above shows the same output when using either forEach() method.

However, Lodash's _.forEach() method is slightly faster and more efficient as it has additional features such as being able to break out of a loop, handle exceptions, and provide more control over iteration.

Code explanation

• const arr = [1,2,3]; - declaring an array of numbers
• arr.forEach(el => console.log(el)); - using the native forEach() method to iterate through the array and log each element to the console
• _.forEach(arr, el => console.log(el)); - using Lodash's _.forEach() method to iterate through the array and log each element to the console
