How do you end a function?
Unlike the return statement, it will cause a program to stop execution even in a function. And the exit() function can also return a value when executed, like the return statement. So the C family has three ways to end the program: exit(), return, and final closing brace.
The return statement stops the execution of a function and returns a value from that function.
How do I stop a function from clicking?

Does break end function?
Short Answer. Break terminates execution of a loop or switch statement and hands over control to next statement after it. Return terminates execution of the current function and passes control to the statement immediately after the function call.
What is a return function?
A return is a value that a function returns to the calling script or function when it completes its task. A return value can be any one of the four variable types: handle, integer, object, or string. The type of value your function returns depends largely on the task it performs.
Is there an end function in Python?
Python’s print() function comes with a parameter called ‘end’. By default, the value of this parameter is ‘n’, i.e. the new line character. You can end a print statement with any character/string using this parameter.
When a return statement is used in a function body, the execution of the function is stopped. If specified, a given value is returned to the function caller. For example, the following function returns the square of its argument, x , where x is a number. If the value is omitted, undefined is returned instead.
return false inside a callback prevents the default behaviour. For example, in a submit event, it doesn’t submit the form. return false also stops bubbling, so the parents of the element won’t know the event occurred.
How does a function return a value?
To return a value from a function, you must include a return statement, followed by the value to be returned, before the function’s end statement. If you do not include a return statement or if you do not specify a value after the keyword return, the value returned by the function is unpredictable.
What is event stopPropagation ()?
stopPropagation() The stopPropagation() method of the Event interface prevents further propagation of the current event in the capturing and bubbling phases. It does not, however, prevent any default behaviors from occurring; for instance, clicks on links are still processed.
How do you start a stop setInterval function?
How do you stop event listeners?

How do you break a while loop?

Is void a function?
Void functions are created and used just like value-returning functions except they do not return a value after the function executes. In lieu of a data type, void functions use the keyword “void.” A void function performs a task, and then control returns back to the caller–but, it does not return a value.
