Package description
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.
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')); // falseCheck 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('!')); // falseValidator is a more comprehensive library for string validation and sanitization. It includes a function to check if a string is alphanumeric among many other validation functions. Compared to is-alphanumerical, validator is more versatile but also larger in size, making is-alphanumerical a lightweight alternative for specific alphanumeric checks.
Is-alphanumeric is another package with a similar purpose, offering functionality to check if strings or characters are alphanumeric. The main difference lies in the implementation details and possibly in performance benchmarks, but both serve the same primary purpose.
