New web designers may wonder whether HTML tags are case sensitive. While the short answer is that HTML tags aren’t case sensitive , there are important rules and best practices to consider when writing HTML markup.

JavaScript is a case-sensitive language . This means that language keywords, variables, function names, and any other identifiers must always be typed with a consistent capitalization of letters. The while keyword, for example, must be typed “while”, not “While” or “WHILE”.

In JavaScript, the while keyword, should be “while”, not “While” or “WHILE”. Case sensitivity is important since it is closely related to HTML , but some methods and events are mentioned differently. Some tags and attributes in HTML have the same name as JavaScript objects and properties.

A script is in plain text and not simply markup like hypertext markup language, that is case insensitive . In JavaScript, the whereas keyword ought to be “while”, not “While” or “WHILE”.

The most basic way to do case insensitive string comparison in JavaScript is using either the toLowerCase() or toUpperCase() method to make sure both strings are either all lowercase or all uppercase .
