What is this?

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

When should I use this?

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.

Install

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>

Use

import {ccount} from 'ccount'

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

API

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

ccount(value, character)

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

Parameters

Types

This package is fully typed with TypeScript.

Compatibility

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.
