Escape string for use in HTML

This module exports a single function, escapeHtml, that is used to escape a string of content such that it can be interpolated in HTML content.

This module will escape the following characters: ", ', &, <, and >.

Note that the escaped value is only suitable for being interpolated into HTML as the text content of elements in which the tag does not have different escaping mechanisms (it cannot be placed inside <style> or <script>, for example, as those content bodies are not HTML, but CSS and JavaScript, respectively; these are known as "raw text elements" in the HTML standard).

Note when using the escaped value within a tag, it is only suitable as the value of an attribute, where the value is quoted with either a double quote character (") or a single quote character (').

var escapeHtml = require('escape-html');
var html = escapeHtml('foo & bar');
// -> foo & bar
