What is this?

This is a tiny package that finds the count of a substring.

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 14.14+, 16.0+), install with npm:

npm install ccount

In Deno with esm.sh:

import {ccount} from 'https://esm.sh/ccount@2'

In browsers with esm.sh:

<script type="module">
  import {ccount} from 'https://esm.sh/ccount@2?bundle'
</script>

Use

import {ccount} from 'ccount'

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

API

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

ccount(value, character)

Get the count of substring in value.

Parameters

• value (string) — content to search in
• substring (string) — substring to look for, typically one character

Returns

Count of substrings in value (number).

Types

This package is fully typed with TypeScript. It exports no additional types.

Compatibility

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

Security

This package is safe.
