In Javascript, void is an operator that specifies to calculate an expression but does not return a value. If you are not familiar with it, refer to void in Javascript in this article as an operator, this operator specifies to calculate an expression but does not return a value.
The format of the void operator is as follows:

2. javascript: void expression
Expression is a standard Javascript expression to be calculated. Parentheses outside the expression are optional, but it is a good habit to write them. (Implement version Navigator 3.0)
You use the void operator to specify the hyperlink. The expression is calculated, but no content is loaded in the current document.

Nothing happens here.
The following code creates a hyperlink. A form is submitted when a user opens a ticket:
Submit a form here
A href = # several methods to differentiate connections from a href = javascript: void (0:

This is why sometimes a long page browsing link is clearly #
Yes to the top
This is not the case with javascript: void (0 ).
Therefore, it is best to call scripts.
Void (0)
