What Is Word Frequency Counter?

The Word Frequency Counter analyzes text and counts how many times each word appears. Results are sorted by frequency (most common first) and include the count and percentage of total words. An optional case-sensitivity toggle lets you choose whether "The" and "the" should be counted as the same word. The tool also shows total word count and unique word count. This is useful for content analysis, SEO keyword research, and understanding word usage patterns.

Technical Guide

The counter extracts words using the regex /\b[\w']+\b/g which matches word characters including apostrophes (for contractions like "don't"). When case-insensitive mode is enabled, the text is lowercased before word extraction. A frequency map (Record<string, number>) counts occurrences. Results are sorted by count in descending order. The output is formatted as a padded table showing word, count, and percentage (count/totalWords * 100). Total words and unique word count are shown at the top of the output.
