This JavaScript function, analyzeString(), analyzes a given string and returns various details about it.

Installation

This function does not require any installation. You can simply include it in your JavaScript code.

Functionality

The analyzeString() function takes a string as input and returns an object containing the following details:

• length: Length of the input string.
• characterCount: Number of characters in the string.
• wordCount: Number of words in the string.
• containsNumbers: Boolean indicating whether the string contains any numeric digits.
• containsSpecialCharacters: Boolean indicating whether the string contains any special characters.
• containsWhitespace: Boolean indicating whether the string contains any whitespace characters.
• isAllUpperCase: Boolean indicating whether the string is entirely uppercase.
• isAllLowerCase: Boolean indicating whether the string is entirely lowercase.
• isPalindrome: Boolean indicating whether the string is a palindrome (reads the same forwards and backwards).

Example

Input

const input = "A man, a plan, a canal, Panama!";
const stringDetails = analyzeString(input);

Expected Output

{
  "length": 30,
  "characterCount": 27,
  "wordCount": 6,
  "containsNumbers": false,
  "containsSpecialCharacters": true,
  "containsWhitespace": true,
  "isAllUpperCase": false,
  "isAllLowerCase": false,
  "isPalindrome": true
}

Additional Functionalities with update 1.1.1

In addition to the functionalities described above, the analyzeString() function now includes the following additional features:

• characterFrequency: Returns an object containing the frequency of each character in the input string.

  Input

  const input = "hello";
  const characterFreq = analyzeString(input).characterFrequency;
  

  Expected Output

  {
    "h": 1,
    "e": 1,
    "l": 2,
    "o": 1
  }
  

• vowelCount: Number of vowels in the string.

  Input

  const input = "hello world";
  const vowelCount = analyzeString(input).vowelCount;
  

  Expected Output

  3
  

• consonantCount: Number of consonants in the string.

  Input

  const input = "hello world";
  const consonantCount = analyzeString(input).consonantCount;
  

  Expected Output

  7
  

• isAnagram: Determines whether two input strings are anagrams of each other.

  Input

  const input1 = "listen";
  const input2 = "silent";
  const isAnagram = analyzeString(input1).isAnagram(input1, input2);
  

  Expected Output

  true
  

• isAntigram: Determines whether two input strings are antigrams of each other.

  Input

  const input1 = "hello";
  const input2 = "world";
  const isAntigram = analyzeString(input1).isAntigram(input1, input2);
  

  Expected Output

  false
  

• countSubstringOccurrences: Counts the number of occurrences of a substring in the input string.

  Input

  const input = "hello world hello";
  const substring = "hello";
  const count = analyzeString(input).countSubstringOccurrences(input, substring);
  

  Expected Output

  2
  

• startsWith: Checks if the input string starts with a certain substring.

  Input

  const input = "hello world";
  const substring = "hello";
  const startsWith = analyzeString(input).startsWith(input, substring);
  

  Expected Output

  true
  

• endsWith: Checks if the input string ends with a certain substring.

  Input

  const input = "hello world";
  const substring = "world";
  const endsWith = analyzeString(input).endsWith(input, substring);
  

  Expected Output

  true
  

• longestWord: Returns the longest word in the input string.

  Input

  const input = "hello beautiful world";
  const longestWord = analyzeString(input).longestWord;
  

  Expected Output

  "beautiful"
  

• reverseWords: Reverses the order of words in the input string.

  Input

  const input = "hello world";
  const reversedWords = analyzeString(input).reverseWords(input);
  

  Expected Output

  "world hello"
  

These additional functionalities enhance the capabilities of the analyzeString() function, providing users with a comprehensive tool for string analysis and manipulation.
