๐งต Provides ways of checking whether a String is present in an Array of Strings using custom Comparators. ๐
I work hard for every project, including this one and your support means a lot to me!
Consider buying me a coffee. โ
Thank you for supporting my efforts! ๐๐

Install it by executing:
npm i "@igor.dvlpr/str-is-in"A type named ComparatorCallback is exposed and used as a signature for the comparator parameter of the strIsIn() function.
type ComparatorCallback = (entry: string, value: string) => booleanstrIsIn(value: string, entries: string[], comparator?: ComparatorCallback): booleanChecks whether the given String is present in the provided array of Strings.
findMatch.full(value: string, entries: string[]): stringPerforms a case-insensitive and full-matching search for a given value inside an array of values and returns the found match (with the original case being preserved). If none is found an empty string is returned.
findMatch.partial(value: string, entries: string[]): stringPerforms a case-insensitive and partial-matching search for a given value inside an array of values and returns the found match (with the original case being preserved). If none is found an empty string is returned.
import { strIsIn, findMatch } from '@igor.dvlpr/str-is-in'
// #1 - use default Comparator, non-existent string, full match
console.log(strIsIn('bin', ['abc', 'cde', 'def', 'binary'])) // prints false
// #2 - use default Comparator, existing string, full match
console.log(strIsIn('bin', ['abc', 'cde', 'bin', 'adc'])) // prints true
// #3 - empty array passed
console.log(strIsIn('bin', [])) // prints false
// #4 - custom Comparator, partial match
console.log(strIsIn('bin', ['abc', 'cde', 'def', 'binary'], (entry, value) => entry.indexOf(value) > -1)) // prints true
// #5 - custom Comparator, partial match
console.log(strIsIn('bin', ['abc', 'cde', 'def', 'HellobinaryWorld'], (entry, value) => entry.indexOf(value) > -1)) // prints true
// #6 - custom Comparator, partial match, non-existent string
console.log(
strIsIn('t', ['abc', 'cde', 'def', 'HellobinaryWorld'], (entry, value) => entry.toLowerCase() === value.toLowerCase())
) // prints false
// #7 - custom Comparator, partial match, existing string, case-insensitive
console.log(strIsIn('WORLD', ['abc', 'cde', 'def', 'world'], (entry, value) => entry.toLowerCase() === value.toLowerCase())) // prints true
// #8 - custom Comparator, partial match, case-insensitive
console.log(
strIsIn(
'WORLD',
['abc', 'cde', 'def', 'HellobinaryWorld'],

) // prints true
// #9 - full match-finding
