How to declare a RegEx with character repetition to match the strings "http", "htttp", "httttp", etc in TypeScript

Answer 1

// Declare the regex pattern
const pattern: RegExp = /^htt+p$/;

// Test strings
const testStrings: string[] = ["http", "htttp", "httttp", "httpp", "htp"];

// Check matches
testStrings.forEach(test => {
    const match: boolean = pattern.test(test);
    console.log(`Matches "${test}": ${match}`);
});


 
// Matches "httpp": True or false, depending on how matches() method works
 
 
/*
run:
 
"Matches "http": true" 
"Matches "htttp": true" 
"Matches "httttp": true" 
"Matches "httpp": false" 
"Matches "htp": false" 
 
*/
