what is JavaScript Reserved Words guide with code example


 

In JavaScript, there are certain words that have special meaning and cannot be used as variable names, function names, or identifiers. These words are called "reserved words". Here's a list of JavaScript reserved words:

java
abstract arguments await boolean break byte case catch char class const continue debugger default delete do double else enum eval export extends false final finally float for function goto if implements import in instanceof int interface let long native new null package private protected public return short static super switch synchronized this throw throws transient true try typeof var void volatile while with yield

It's important to note that reserved words cannot be used as variable names, function names, or identifiers. For example, the following code will produce an error:

csharp
var let = 10;

In this example, the reserved word let is used as a variable name, which is not allowed in JavaScript. To avoid this error, you can choose a different variable name:

csharp
var myVariable = 10;

In this example, the variable myVariable is used instead of the reserved word let.

In summary, reserved words are words that have special meaning in JavaScript and cannot be used as variable names, function names, or identifiers. It's important to be aware of these words when writing JavaScript code to avoid syntax errors.
