Unlike the variables, the constants are elements in the script that can not be changed. Like the variables, they can contain:

• numbers
• characters, letters
• character strings
• number sets
• character sets

Trying to edit the constants will give an error, because the constants' contents can not be edited.

Declaration

The constants are declared as it follows:

const name=value;
      name2=value;

For example:

const a=5;
      vector=[1,2,3..500];
      letters=['A'..'Z'];
