This article introduces the knowledge of "is javascript case-sensitive?". Many people will encounter such a dilemma in the operation of actual cases, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Distinguish. Javascript is a strictly case-sensitive language. When entering keywords, variable names, function names and all identifiers, it must adopt a consistent character case form; in order to avoid input confusion and syntax errors, code is generally written in lowercase characters.

The operating environment of this tutorial: windows7 system, javascript1.8.5 version, Dell G3 computer.

Javascript is case sensitive.

Javascript is a strictly case-sensitive language, so Hello and hello are two different identifiers.

When entering keywords, variable names, function names, and all identifiers, you must use consistent character case.

To avoid typing confusion and syntax errors, it is recommended that code be written in lowercase characters, and uppercase in the following special cases:

1. The first letter of the constructor is recommended to be capitalized. Constructors are different from ordinary functions.

Example

The following example calls the predefined constructor Date (), creates a time object, and then converts the time object to a string to display.

D = new Date (); / / get the current date and time [xss_clean] (d.toString ()); / / display date

2. If the identifier consists of multiple words, consider using camel nomenclature-except for the first word, the first letter of the latter word is capitalized. For example:

TypeOf (); printEmployeePaychecks ()

Tip: the above are all established general habits and do not constitute a mandatory requirement. Users can name them according to their personal habits.

Note, however, that HTML is not case-sensitive, which is easily confused because it is closely related to the client-side JavaScript. Many JavaScript objects and attributes have the same name as the HTML tags and properties they represent.

These tags and property names can be entered in any case in HTML, but they are usually lowercase in JavaScript. For example, in HTML, the event handler nature onclick is usually declared as onClick, but only onclick can be used in JavaScript code.
