How does lodash.forEachRight work?

The lodash.forEachRight function is a utility function in the Lodash library that is used to iterate over an array or object in reverse order, executing a callback function on each element. When called, lodash.forEachRight takes three arguments: collection: The array or object to iterate over. iteratee: The callback function to execute on each element. thisArg: Optional context object to use as this when executing the iteratee function. The iteratee callback function is called with three arguments for each element: value: The current element being processed. key: The key or index of the current element. collection: The original collection being iterated over. The lodash.forEachRight function iterates over the collection in reverse order, starting with the last element and moving backwards towards the first element. This is different from the lodash.forEach function, which iterates over the collection in forward order. Overall, lodash.forEachRight provides a convenient way to iterate over an array or object in reverse order, allowing you to perform operations such as filtering, mapping, or reducing elements in a specific order.

// ForEachRight -> same as forEach but iterates's from right side.

const _ = require("lodash");

const numbers = [1, 2, 3, 4, 5];

_.forEachRight(numbers, function (value, index) {
  console.log(`Index ${index}: ${value}`);
});

In this example, we have imported the Lodash library using require and defined an array of numbers. We then call lodash.forEachRight with the numbers array and a callback function as arguments. The callback function takes two arguments: value, which is the current element being processed, and index, which is the index of the current element. Inside the callback function, we output a message to the console that includes the index and value of the current element. When executed, this code will output the following to the console: yaml Copy code
