Constructors

Option.of

The primary way to lift nullable values:

Option.of(value);

Input	Result
null	None
undefined	None
any other value	Some(value)

Some

Creates a non-empty option unconditionally:

Some(0);
Some('');
Some(null); // Option<null> — isDefined is true

Use when the value is already known to be present.

None

Singleton empty option:

import { None } from '@ekz/option';

const missing: Option<string> = None;

Also available as Option.None after the module loads.

Do not use new Option()

The constructor is private. Always use Option.of, Some, or None — otherwise an error is thrown.

Static aliases

Option.Some(1);
Option.None;

Equivalent to the exported Some function and None constant.
