Contain Validator

This library is small but easy to use. The purpose of this library is to check if a string contains a sub string. The library also do case sensitive checking.

Validation processes

The code contains two methods to check it a string contains as substring.

Compare method 1

This method is case sensative so both string and sub string must be the same case.

Compare method 2

This method is not case sensative so both string and sub string can contain any case.

Code sample

This following code is actually how I tested that all seven methods correctly functioned as intended, is also provided in this libery.

import subStringIsValid from './node_modules/@creepycoder/containvalidator/containvalidator.js';

console.log( "Testing Condition 1 Passed = " + subStringIsValid( "Hallo world" , "world" , true ) );
console.log( "Testing Condition 2 Passed = " + subStringIsValid( "Hallo world" , "World" , false ) );
console.log( "Testing Condition 3 Passed = " + !subStringIsValid( "Hallo world" , "beans" , true ) );
console.log( "Testing Condition 4 Passed = " + subStringIsValid( "Hallo world" , "world" ) );
console.log( "Testing Condition 5 Passed = " + !subStringIsValid( "Hallo world" , "World" ) );

The results will look as follows

Testing Condition 1 Passed = true
Testing Condition 2 Passed = true
Testing Condition 3 Passed = true
Testing Condition 4 Passed = true
Testing Condition 5 Passed = true
