Perfmon how to resize counter frame at bottom of the window
Workaround:
When Performance Monitor opens, one or more default counters are in the legend pane and only the first is visible. The legend pane is not resizable.
Right click in the legend pane and select Remove All Counters.
Re-add the desired counters and and the legend pane resizes to fit all/most as needed.

JavaScript Refresh Time
There are 7 basic types in JavaScript.
number for numbers of any kind: integer or floating-point.
string for strings. A string may have one more more characters, there’s no separate single-character type.
boolean for true/false.
null for unknown values – a standalone type that has a single value null.
undefined for unassigned values – a standalone type that has a single value undefined.
object for more complex data structures.
symbol for unique identifiers.
The typeof operator allows to see which type is stored in the variable.
Two forms: typeof x or typeof(x).
Returns a string with the name of the type, like "string".
For null returns "object" – that’s the error in the language, it’s not an object in fact.
In the next chapters we’ll concentrate on primitive values and once we’re familiar with that, then we’ll move on to objects.
