Adverb Highlighter Find and highlight adverbs in your writing for stronger prose.

The tool's algorithm relies on a combination of a curated list of common adverbs and pattern matching to identify potential adverbs in the input text. It utilizes the Set data structure from JavaScript to store over 150 common adverbs for efficient lookups. When processing the text, it splits the input into individual words using regular expressions and filters out empty strings. Each word is then cleaned by converting it to lowercase and removing non-alphabetic characters. The tool checks if the cleaned word matches any of the known adverbs in the Set or if it ends with the suffix -ly and has a length greater than 3 characters, indicating a potential adverb.

The identified adverbs are stored in an object where each key is the adverb and its corresponding value is the frequency of occurrence. This data structure allows for efficient sorting and calculation of the adverb density percentage. The tool uses the React library's useCallback hook to memoize the onProcess function, which improves performance by preventing unnecessary re-renders. When generating the highlighted text, it iterates over each word in the input text and wraps identified adverbs with >>> and <<< markers.

The frequency analysis is performed by sorting the adverb object entries in descending order based on their counts. This sorted list is then used to generate the adverb frequency report, which displays the top 20 most frequent adverbs along with their occurrence counts. If there are more than 20 unique adverbs, it appends a message indicating the number of additional adverbs found. The tool also calculates the adverb density percentage by dividing the total number of adverbs by the total number of words and multiplying by 100.

The output report includes the total word count, adverb count, unique adverb count, and the calculated adverb density percentage. Based on this density percentage, it provides writing tips and suggestions for improving the text, such as replacing certain adverb-verb combinations with stronger verbs. The React-based TextToolLayout component is used to render the input field, output label, and the processed result, providing a user-friendly interface for writers to analyze and refine their work.
