What are bytes's main functionalities?

Parse byte size strings

This feature allows you to parse a string representing a byte size into an integer number of bytes. For example, passing '1000KB' will return 1000000.

"1000KB" // returns 1000000

Format bytes into strings

This feature allows you to format an integer number of bytes into a string with a unit. For example, passing 1024 will return '1KB'.

1024 // returns '1KB'

Specify the number of decimal places

This feature allows you to specify the number of decimal places when formatting bytes into a string. For example, passing an object with 1000 bytes and 1 decimal place will return '1.0KB'.

{ bytes: 1000, decimalPlaces: 1 } // returns '1.0KB'

Specify the unit of bytes

This feature allows you to specify the unit when formatting bytes. For example, passing an object with 1024 bytes and 'kB' as the unit will return '1kB'.

{ bytes: 1024, unit: 'kB' } // returns '1kB'
