Text Analysis

This code is a module in JavaScript that provides text analysis functionality. From an end-user's perspective, it helps users to analyze English text and extracts various pieces of information about the composition of the text.

Counting Vowels and Consonants

Primarily, the module counts the number of vowels and consonants in the given text. It does this by iterating through each character in the entered text string. If the character is included in the predefined list of vowels or consonants, it increases the corresponding count. In terms of casing, both lower and upper case characters are considered, making this function case-insensitive.

Building a Character Histogram

Moreover, the code also builds a histogram of all alphabet characters (both lower and upper case) found in the text. This histogram is a representation of the letter distribution in the text. Each distinct alphabetic character found in the text is made a key in the histogram object, and its corresponding value gets incremented each time that character is encountered in the text.

Returnstatement

Finally, the function returns an object containing the vowel count, the consonant count, and the histogram. This implies that the result of the function is easily accessible and can be further manipulated or displayed for end-users, thereby enabling a deeper understanding of the text composition.

The result gives a comprehensive summary of the text, providing users with an insight into the frequency of letters used in their text, including the comparative ratio of vowels to consonants. This could be useful in fields like linguistics, cryptography or even for plain text analysis.
