JavaScript Evolution Continues

JavaScript continues to evolve with new features being added regularly. ES2024 brings several exciting additions that make the language more powerful and developer-friendly.

Array Grouping Methods

One of the most anticipated features is the native array grouping methods:

const fruits = [
                                    { name: 'apple', type: 'fruit' },
                                    { name: 'carrot', type: 'vegetable' },
                                    { name: 'banana', type: 'fruit' }
                                ];

                                const grouped = Object.groupBy(fruits, ({ type }) => type);
                                console.log(grouped);

Promise.withResolvers()

This new method provides a more convenient way to create promises:

const { promise, resolve, reject } = Promise.withResolvers();

                                // Use resolve and reject as needed
                                setTimeout(() => resolve('Success!'), 1000);

String Methods

New string methods make text manipulation easier and more intuitive.
