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][esm].
In Node.js (version 12.20+, 14.14+, or 16.0+), install with [npm][]:

``sh
npm install ccount
`

In Deno with [Skypack][]:

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

In browsers with [Skypack][]:

`html

`

Use

`js
import {ccount} from 'ccount'

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

There is no default export.
