normalize

function normalize(path: string): string;

A . is dropped, a .. removes the segment before it, repeated separators collapse, and a trailing separator is removed.

The result always starts at the root: normalize("a/b") is "/a/b". Use join when a relative path has to stay relative.

Parameters

Parameter	Type	Description
`path`	`string`	The path to normalise.

Returns

string — the normalised path.

Examples

Normalising

normalize("a/./b/../c"); // => "/a/c"
normalize("/a/b/../c/"); // => "/a/c"
