What is is-alphanumerical?
The is-alphanumerical npm package is designed to check if a given input (string or character) is alphanumeric, meaning it consists of letters and numbers only. This can be particularly useful for validating user input, parsing content, or filtering data in applications where alphanumeric strings are required or expected.
What are is-alphanumerical's main functionalities?
Check if a string is alphanumeric
This feature allows you to verify if an entire string is alphanumeric. It returns true if the string contains only letters and numbers, and false otherwise.
"use strict"; var isAlphanumerical = require('is-alphanumerical'); console.log(isAlphanumerical('abc123')); // true console.log(isAlphanumerical('abc!123')); // false
Check if a single character is alphanumeric
This feature enables checking whether a single character is alphanumeric. It's useful for parsing or iterating through strings character by character to validate or process each one.
"use strict"; var isAlphanumerical = require('is-alphanumerical'); console.log(isAlphanumerical('a')); // true console.log(isAlphanumerical('!')); // false
