\n\n- Use of the API is unsafe.
\n- An improved alternative API is available.
\n- Breaking changes to the API are expected in a future major release.
\n
\nNode.js uses three kinds of Deprecations:
\n\n- Documentation-only
\n- Runtime
\n- End-of-Life
\n
\nA Documentation-only deprecation is one that is expressed only within the\nNode.js API docs. These generate no side-effects while running Node.js.\nSome Documentation-only deprecations trigger a runtime warning when launched\nwith --pending-deprecation flag (or its alternative,\nNODE_PENDING_DEPRECATION=1 environment variable), similarly to Runtime\ndeprecations below. Documentation-only deprecations that support that flag\nare explicitly labeled as such in the\nlist of Deprecated APIs.
\nA Runtime deprecation will, by default, generate a process warning that will\nbe printed to stderr the first time the deprecated API is used. When the\n--throw-deprecation command-line flag is used, a Runtime deprecation will\ncause an error to be thrown.
\nAn End-of-Life deprecation is used when functionality is or will soon be removed\nfrom Node.js.
