Funciones y variables JavaScript
/*A function is like an operation, you pass two or more values/variables
into it, it will output a value (if return is used).
Also, you will not have to redeclare the parameters if you used arguments. */
/* A global variable can be accessed anywhere including in curly braces { }.
You do not have to list them as an argument however it is recommended */
/* | scroll down |
v v */
/* You will opt a global variable into an argument if
you want it to become a different variable in the function */
/*Use*/ let /*and*/ const /*more often because it will not allow you to
declare it again*/
/*Parameters are like the placeholder variables for the variables
outside the function being used as arguments*/
// Local variables(like in functions) take priority over global variables
/*The */return/* operator will output a value such as */ 4, "string",
true /*etc. this will not be assigned to a variable unless you do assign it
yourself. */
/*If a*/ return /*operator is not used it will change the global variable
instead (if there is one).*/
// A good explenation on global and local variables is below
