[FIXED] What is `^` in Visual Studio Code key bindings notation

Issue

I'd like to open Source Control with a keyboard shortcut.

From the tooltip I can see, that a shortcut exists: tooltip shows the shortcut (^ shift G)

My problem: How do I type the caret character? On my keyboard it's (shift + 6). However this does not work for shortcuts.

Solution

In some environments ^ stands for the Control key. Visual Studio Code uses that notation on its MacOS version.

[FIXED] What is "?:" notation in JavaScript?

Issue

I found this snippet of code in my travels in researching JSON:

var array = typeof objArray != 'object' ? JSON.parse(objArray) : objArray;

I'm seeing more and more of the ? and : notation. I don't even know what it is called to look it up! Can anyone point me to a good resource for this? (btw, I know what != means).

Solution

It's called a Conditional (ternary) Operator. It's essentially a condensed if-else.

So this:

var array = typeof objArray != 'object' ? JSON.parse(objArray) : objArray;

...is the same as this:

var array;
if (typeof objArray != 'object') {
    array = JSON.parse(objArray);
} else {
    array = objArray;
}
