Measuring String Length

  • The len() function in Python allows us to find the length of a string
  • Use '.length' in JavaScript to do this as well

    • Sample Hack - String Analyzation

    • Determine metrics about strings (length, chars, palidrome(?), etc.)
    %%js
const string1 = "Brawl Stars is a fun game!";
const string2 = "Star Brawl war Brats";


console.log("String 1: " + string1);
const length1 = string1.length;
console.log("Length: " + length1);


function countVowels(inputString) {
    const vowels = 'aeiouAEIOU';
    let count = 0;
    for (const char of inputString) {
        if (vowels.includes(char)) {
            count++;
        }
    }
    return count;
}


console.log("Vowel Count: " + countVowels(string1));


function averageWordLength(inputString) {
    const words = inputString.split(/\s+/);
    if (words.length === 0) {
        return 0;
    }
    const totalLength = words.reduce((sum, word) => sum + word.length, 0);
    return totalLength / words.length;
}


console.log("Average Word Length: " + averageWordLength(string1));


function isPalindrome(inputString) {
    const sanitizedString = inputString.replace(/\s+/g, '').toLowerCase();
    return sanitizedString === sanitizedString.split('').reverse().join('');
}


console.log("Palindrome or Not? " + isPalindrome(string1));
console.log("String 2: " + string2);
const length2 = string2.length;
console.log("Length: " + length2);
console.log("Vowel Count: " + countVowels(string2));
console.log("Average Word Length: " + averageWordLength(string2));
console.log("Palindrome or Not? " + isPalindrome(string2));
