['C', 'h', 'a', 'r', 's'] in 'String'

🪐 Provides ways of testing whether an array of chars is present inside a given String. ☄

💖 Support further development

✨ Since v.2.0.0 chars-in-string is a hybrid module that supports both CommonJS (legacy) and ES modules, thanks to Modern Module.

API

An enum is available publicly, used for setting the position of the search, see more below. 👇

enum Position = {
  Any,
  Start,
  End
}

It allows you define where the matching should occur, at the beggining of the String, at the end or anywhere (default).

function charsInString(characters: string[], string: String, position = Position.Any, caseSensitive = true): boolean

characters: string[] - the characters to search for, expects a single character per entry, if multiple are found it will take the first one,

string: String - the String which needs to be checked,

[position: Position=Position.Any] - controls where the matching should occur, at the beggining of the String, at the end or anywhere (default),

[caseSensitive: boolean=true] - controls whether the search is case-sensitive, defalts to true.

function stringsInString(strings, string, position = Position.Any, caseSensitive = true

strings[]: string[] - the strings to search for,

string: String - the String which needs to be checked,

[position: Position=Position.Any] - controls where the matching should occur, at the beggining of the String, at the end or anywhere (default),

[caseSensitive: boolean=true] - controls whether the search is case-sensitive, defalts to true.

Usage

Install it by:

npm i "@igor.dvlpr/chars-in-string"

and then use it like:

const { charsInString, stringsInString, Position } = require('@igor.dvlpr/chars-in-string')

console.log(charsInString([], '')) // prints false

console.log(charsInString([], 'test')) // prints false

console.log(charsInString([':', ','], '')) // prints false

console.log(charsInString([':', ','], 'hello:world')) // prints true

console.log(charsInString([':', ',', '^'], 'helloworld^')) // prints true

console.log(charsInString([':', ',', '^'], 'helloworld')) // prints false

console.log(stringsInString(['abc', 'owom', 'wqp', 'world', 'hel'], 'helloworld', Position.Start)) // prints true
