Number literals, according to JavaScript syntax, can be written with or without the decimal point. There are a few types of literals we use, and they have their own rules to be followed. Literals define fixed values used in JavaScript. Note: the hyphens method does not work in JavaScript. Keep in mind though that in JavaScript the identifier name usually begins with a lowercase letter ( firstName) ![]() Using if-else statements for this purpose will be less efficient over switch case. Throughout the history of programming, there have been three most popular methods to achieve that: hyphens ( first-name), underscores ( first_name), and camel case ( FirstName).Ĭamel case is the default identifier writing method in JavaScript and many other programming languages. The JavaScript switch case statement is used for decision-making purposes. Whenever case sensitivity is relevant, it's important to have a clear standard of writing names that consist of more than one word. In programming, a switch statement is a control-flow statement that tests the value of an expression against multiple cases.Note: same rules apply to keywords and other identifiers as well. I'll also help you figure out if they're a good option to use in your code. In this article, I'll explain what switch statements are and how they work. ![]() Take a look at the example below – instead of using this long if else statement, you might choose to go with an easier to read switch statement. Switch statements can have a cleaner syntax over complicated if else statements. There are times in JavaScript where you might consider using a switch statement instead of an if else statement.
