Definition

An offset describes how much of any data you would like to skip in a list before you begin some form of processing.

Example

🚫 Wrap Code📋 Copy
01: [
02:     1 => 'Person 1',
03:     2 => 'Person 2',
04:     3 => 'Person 3',
05:     4 => 'Person 4',
06:     5 => 'Person 5',
07:     6 => 'Person 6',
08:     7 => 'Person 7',
09:     8 => 'Person 8',
10:     9 => 'Person 9',
11: ]

Take the list shown above, the statement "Offset by 3 and fetch a size of 2" will mean we will skip the first three records and fetch two items after that. This gives us items 4 'Person 4' and 5 'Person 5'.

Summary

Offsets are commonly used in pagination [→] to skip over to interested pages.
