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
