Consequently, can a function and a variable have the same name?So finally, the answer is yes you can declare variable of same name as that of function but you shouldn’t since you may get an error or a warning message by the compiler.Also Know, what happens if a parameter name is the same as the name of a variable defined outside of any function? Global, Local and nonlocal Variables. So when you define variables inside a function definition, they are local to this function by default. This means that anything you will do to such a variable in the body of the function will have no effect on other variables outside of the function, even if they have the same name Also, can we have two functions with the same name in JavaScript? JavaScript supports overriding not overloading, meaning, that if you define two functions with the same name, the last one defined will override the previously defined version and every time a call will be made to the function, the last defined one will get executed.Why are global variables bad JavaScript?Global variables and function names are an incredibly bad idea. The reason is that every JavaScript file included in the page runs in the same scope.
