In Apps Script, variables & constants are used to store and manage data.
A variable is a name that represents a value that can be changed during the execution of a script, while a constant is a name that represents a value that cannot be changed during the execution of a script.
To declare a variable or constant in Apps Script, you can use the keywords “var” and “const” respectively followed by the name of the variable or constant and its initial value (if any). For example, to declare a variable named “count” and assign it an initial value of 0, you would write:
var count = 0;
To declare a constant named “PI” with a value of 3.14159, you would write:
const PI = 3.14159;
Best practices for using variables and constants in Apps Script include:
- Use descriptive names for variables and constants to improve code readability.
- Declare variables and constants at the beginning of a script or function to make it easier to understand the flow of data.
- Initialize variables and constants with appropriate default values.
- Use constants for values that should not be changed during the execution of a script.
- Avoid creating unnecessary variables and constants to minimize memory usage.
By following these best practices, you can write clean and efficient code in Apps Script.
