How to define arrays in javaScript
Use the keyword var to define var Array name = new Array ()
For example:
Var array1 = new Array ("a", "B", "c ");

Define an array with a length of 3:
Var array2 = new Array (3 );

In JavaScript, how does one define a one-dimensional Array?
String str = ""; // define a String
Str = "He eats no fish and plays the qame"; // value assignment
String [] A = str. split (""); // group by Space
The result is A [0] = He A [1] = eats A [2] = no A [3] = fish A [4] = and A [5] = palys [6] = theA [7] = qame
The split () method separates strings into arrays by specified characters!
