How to Fix JavaScript Void 0

From a layman’s point of view, void means an empty space. A space holding nothing. But in programming like JavaScript or any other programming language, void means the command to return nothing. So, when you are writing a JavaSript code, and you want the statement or function to return a particular data type, you can simply use the void to return nothing when the statement or function is satisfied, so, this is exactly what JavaScript void 0 means.

JavaScript Void 0 Meaning

JavaScrip void 0 meaning is similar to the English definition. It means that a function or statement should return void as the statement or function primitive value while evaluating the HTML documents.

Void 0 is used by programmers to prevent any side effects that can result from inserting an expression in an HTML page. In most cases, JavaScript void 0 is used when citing URLs or hyperlinks in an HTML document. So, when users or the programmer clicks on the link, a new page will open or reload the page.

However, if you are calling JavaScript code via the link, you need not refresh or reload the page and at this juncture, you can use JavaScript:void(0).

So, JavaScript void 0 meaning that the statement or function should return an undefined primitive value as this will prevent your browser from refreshing the page or opening a new tab when you call it through the JavaScript statement.
