A JavaScript variable is a container for storing data values. To declare a global variable, you can use the var at global scope like this: let yourGlobalVariable = "global value"; //global variable function displayGlobalVal() { console .log (yourGlobalVariable); //global variable , result is "global value" } displayGlobalVal (); JavaScript Function Scope.
