This package is a small utility that helps you find how frequently a substring occurs in another string.

I find this particularly useful when generating code, for example, when building a string that can either be double or single quoted. I use this utility to choose single quotes when double quotes are used more frequently, and double quotes otherwise.

This package is ESM only. In Node.js (version 12.20+, 14.14+, or 16.0+), install with npm:

npm install ccount

In Deno with Skypack:

import {ccount} from 'https://cdn.skypack.dev/ccount@2?dts'

In browsers with Skypack:

<script type="module">
  import {ccount} from 'https://cdn.skypack.dev/ccount@2?min'
</script>

import {ccount} from 'ccount'

ccount('foo(bar(baz)', '(') // => 2
ccount('foo(bar(baz)', ')') // => 1

This package exports the following identifier: ccount. There is no default export.

Count how often a character (or substring) is used in a string.

• value (string) — value to search in
• character (string) — character (or substring) to look for

number — number of times character occurred in value.

This package is fully typed with TypeScript.

This package is at least compatible with all maintained versions of Node.js. As of now, that is Node.js 12.20+, 14.14+, and 16.0+. It also works in Deno and modern browsers.

This package is safe.

• wooorm/longest-streak — count of longest repeating streak of character in value
• wooorm/direction — detect directionality: left-to-right, right-to-left, or neutral
