Word Counter and Character Counter

A Character is generally one of a limited number of symbols, including the alphabets, numbers. Characters are typically combined to form strings.

To count number of characters in the text can be counted by getting the length of the text. To count number of characters without space in the text can be counted by removing space by using regex in replace method like this replace(/\s+/g, '') in text and then getting length of text

Characters includes Lowercase (a-z),Uppercase (A-Z), Number (0-9) , Symbols ( ! # $ % & ' * + - / = ? ^ _ ` { | } ~ @) and Space.

Characters without space (hello), Characters withspace (hello world) here having space between words,

A word is generally group of characters that expresses a particular meaning.

To count number of words in a text, split them, then use regex and replace all linebreaks in a string (replace(/[\t\n\r\.\?\!]/gm, " "), Remove the space character if present, then the length of that string gives the word count
