How to Use Word Frequency Counter
Word Frequency Counter Formula / How It Works
Behind the scenes, this Word Frequency Counter runs high-performance client-side Javascript code in your web browser. When you input values into the fields, the calculation engine processes the data using the standard math logic: Extracts words using regex, maps them into a key-value counter, and sorts results by counts.. Specifically, it normalizes casing, extracts individual words using regex, maps them to a count object, and sorts them by frequency density. Because the processing happens locally on your device rather than on a remote cloud server, latency is reduced to zero milliseconds. This browser-based execution is the most secure method for online calculations, preserving your complete data privacy while providing instant results.
For example, let's look at the sentence "write clean code and write code fast" evaluated by the tool. By entering these values into the tool, you will get a list showing "write" (2 times, 25%), "code" (2 times, 25%), "clean" (1 time, 12.5%), "fast" (1 time, 12.5%) instantly.
