unescapeHtml

Unescapes the HTML entities &, <, >, ", and ' back to &, <, >, ", and '.

This is the exact inverse of escapeHtml — it only recognizes the five entities that function produces, not the full HTML entity set (no  , no numeric code points beyond ', etc.).

Available since v3.0.0

Import

import { unescapeHtml } from '@helpers4/string';
// or, from the all-in-one package (same code, one install):
import { unescapeHtml } from 'helpers4/string';

Signature

unescapeHtml(str: string): string

Parameters

Parameter	Type	Description
str	string	The string to unescape

Returns

string — The unescaped string

Examples

Unescape HTML entities back to their original characters

Inverse of escapeHtml — turns <, >, &, ”, ’ back into < > & ” ’.

unescapeHtml('<b>bold</b>')
// => '<b>bold</b>'

Unrecognized entities are left untouched

Only the five entities escapeHtml produces are unescaped — not the full HTML entity set.

unescapeHtml('a b')
// => 'a b'  (unchanged)
