What does javascript mean?

JavaScript is an object-based and event-driven scripting language with security performance.

Like other languages, Javascript scripting languages have their own basic data types, expressions and arithmetic operators, as well as the basic program framework of programs. Javascript provides four basic data types and two special data types for processing data and words. Variables provide a place to store information, while expressions can complete more complex information processing.

The difference between JavaScript and Java

Java code must be compiled before it can be executed, while JavaScript does not need to be compiled, but only needs to be interpreted and executed by the browser.

Although both Java and JavaScript can be executed on the server and client, most of Java runs on the server and most of JavaScript runs on the client.

JavaScript uses loose data types, while Java uses strict data types.
