Improve the readability of large numbers in JavaScript

The article discusses numeric separators in JavaScript, which are a new feature introduced in ECMAScript 2021. These separators allow programmers to make long numbers more readable. Previously, developers often had to rely on adding spaces or using underscores to enhance clarity. Now, with the introduction of numeric separators, programmers can use underscores to separate numbers into groups. This functionality is incredibly useful when dealing with large values, such as when creating financial applications. The article thoroughly explains how to correctly use the separators and provides examples of their applications in practice.
