Package description
The is-lower-case package is a simple utility that allows you to check if a given string is in lower case. It is useful when you need to validate text input or ensure that strings conform to certain case requirements.
Check if a string is in lower case
This feature allows you to verify if a string is entirely composed of lower case letters. The function returns a boolean value.
const isLowerCase = require('is-lower-case');
isLowerCase('string'); // true
isLowerCase('String'); // false
isLowerCase('STRING'); // falseThis package provides the opposite functionality of is-lower-case. It checks if a string is in upper case instead of lower case. It is useful for similar scenarios where text case needs to be validated.
Validator is a more comprehensive string validation and sanitization library. It includes functions to check if a string is in lower case (isLowercase) as well as many other validation functions, making it a more versatile choice if you need additional validation capabilities.
The case package is a comprehensive utility for transforming and testing the case of strings. It includes methods for converting to lower case, upper case, and other case styles, as well as checking the case of strings. It offers more features than is-lower-case for case manipulation.
