wordcountFilter: Core Function and Role

wordcountThe filter is specifically used to count the number of words in a given string.It defines words by recognizing spaces in strings and treats each sequence separated by spaces as an independent word.Finally, it will return an integer representing the total number of words counted.

This filter is very practical in scenarios where quantitative analysis of text is required.For example, you can quickly understand the overall length of an article, provide the user with an estimated content reading time, or use it as a word limit reference in some content submission scenarios.
