"Arrays are special container objects. Arrays can hold many values under a single name. Each value in the array " + "Netscript arrays have the same properties and functions as javascript arrays. For information see javascripts <a href=\"https://www.w3schools.com/js/js_arrays.asp\">array</a> documentation.<br><br>"+
"can be accessed using an index number. The following example shows how to declare an array: <br><br>" +
"thisIsAnArray = Array[1, 2, 3, 'bitburner!', false];<br><br>" +
"Note that the values in an array can be different types. To access this array we just declared, we can use the index " +

"print(thisIsAnArray[0]); <br>" +
"thisIsAnArray[1] = 5;<br>" +

"Note that arrays are indexed starting at index 0. Using an index that is too large or less than 0 will result in an " +
"out of bounds runtime error. <br><br>" +
"If an element in an array is assigned to a value that includes a variable, then it holds a reference to that variable. " +
"What this means is that if the variable changes, the array element will also change accordingly. For example:<br><br>" +
"x = 10;<br>testArr = Array[x];<br>print(testArr[0]);<br>x = 20;<br>print(testArr[0]);<br><br>" +
