Kotlin introduces a unique feature that allows developers to use underscores in numeric literals, making large numbers significantly easier to read. For instance, instead of writing '50000', one can write '50_000', which visually separates the digits and enhances clarity. This approach is akin to using commas in English for large numbers, where '50,000' is easier to comprehend than '50000'. Such features are particularly beneficial for beginners who are learning to code in Kotlin, as they promote better coding practices and improve overall code readability.

Kotlin 引入了一个独特的功能，允许开发者在数字字面量中使用下划线，使得大数字的阅读变得更加容易。例如，使用 '50_000' 代替 '50000'，这样可以在视觉上分隔数字，提高清晰度。这种方法类似于在英文中使用逗号表示大数字，'50,000' 比 '50000' 更容易理解。这些特性对于学习 Kotlin 的初学者尤其有益，因为它们促进了更好的编码实践，并改善了整体代码的可读性。
