Javascript - var function scope.

var variables are ‘function scope.’ What does this mean? It means they are only available inside the function they’re created in, or if not created inside a function, they are ‘globally scoped.’

var funcs = [];
// let's create 3 functions
for (var i = 0; i < 3; i++) {
  // and store them in funcs
  funcs[i] = function() {
    // each should log its value.
    console.log("My value: " + i);
  };
}
for (var j = 0; j < 3; j++) {
  // and now let's run each one to see
  funcs[j]();
}
