How can I determine if a variable is an array? [JS NG TS CS JQ] : <p>Sometimes it is necessary to determine what type of data a variable contains, in this specific case we are talking about the <code>Array</code> type.</p>

<p>How can I end in the different scenarios if the variable is <code>Array</code> type?
I'm talking about scenarios, I'm talking about <code>jQuery</code>, <code>Angular</code>, <code>TypeScript</code>, <code>CoffeeScript</code>, etc.</p>
