These generate no side-effects while running Node.js.\nSome Documentation-only deprecations trigger a runtime warning when launched\nwith <a href=\"cli.html#--pending-deprecation\"><code>--pending-deprecation</code></a> flag (or its alternative,\n<code>NODE_PENDING_DEPRECATION=1</code> environment variable), similarly to Runtime\ndeprecations below. Documentation-only deprecations that support that flag\nare explicitly labeled as such in the\n<a href=\"#list-of-deprecated-apis\">list of Deprecated APIs</a>.</p>\n<p>A Runtime deprecation will, by default, generate a process warning that will\nbe printed to <code>stderr</code> the first time the deprecated API is used. When the\n<a href=\"cli.html#--throw-deprecation\"><code>--throw-deprecation</code></a> command-line flag is used, a Runtime deprecation will\ncause an error to be thrown.</p>\n<p>An End-of-Life deprecation is used when functionality is or will soon be removed\nfrom Node.js.</p>",
