JavaScript(JS) array method - foreach

The forEach() method is an array method in JavaScript that executes a provided function once for each array element. It is a simple way to iterate over an array and perform an action on each element.

Here's the syntax of the forEach() method:

array.forEach(callback);

• array is the array that the forEach() method is called on.
• callback is a function that is called for each element in the array. The function takes three arguments: the current element being processed, its index, and the array that the forEach() method was called on.

The forEach() method does not modify the original array. It returns undefined.

Here's an example of how to use the forEach() method:

let array = ['apple', 'banana', 'cherry'];

array.forEach(function(element) {
  console.log(element);
});

In this example, we have an array array containing the elements ['apple', 'banana', 'cherry']. We use the forEach() method to loop over each element in the array and log it to the console. The output of this code will be:

apple
banana
cherry

Note that you can also use an arrow function instead of a regular function expression, like this:

let array = ['apple', 'banana', 'cherry'];

array.forEach(element => {
  console.log(element);
});

This is a shorter way of writing the same code.
