+The `enum` keyword specifies a validation constraint for an instance, defining a set of permissible values. The value of the `enum` keyword must be an array containing at least one element, and these elements should be unique. The validation succeeds if the value of the instance matches one of the elements in the `enum` array.
+
+_**Note:** Using the `type` keyword along the `enum` keyword is considered an anti-pattern, as `enum` constraints instances tighter than `type`._
+
+## Examples
+
+{{<schema `Schema with string enum`>}}
+{
+  "$schema": "https://json-schema.org/draft/2020-12/schema",
+  "enum": [ "red", "green", "blue" ]
+}
+{{</schema>}}
+
+{{<instance-pass `Instance with value present in the enum is valid`>}}
+"green"
+{{</instance-pass>}}
+
+{{<instance-fail `Instance with value not present in the enum is invalid`>}}
+"black"
+{{</instance-fail>}}
+
+{{<schema `Schema with number enum`>}}
+{
+  "$schema": "https://json-schema.org/draft/2020-12/schema",
+  "enum": [ 2, 46, 100 ]
+}
+{{</schema>}}
+
+{{<instance-pass `Instance with value present in the enum is valid`>}}
+45
+{{</instance-pass>}}
+
+{{<instance-fail `Instance with value not present in the enum is invalid`>}}
+70
+{{</instance-fail>}}
+
+{{<instance-fail `Instance with value having different datatype is invalid`>}}
+"2"
+{{</instance-fail>}}
+
+{{<schema `Schema with mixed-type enum`>}}
+{
+  "$schema": "https://json-schema.org/draft/2020-12/schema",
+  "enum": [ "red", 123, true, { "foo": "bar" }, [ 1, 2 ], null ]
+}
+{{</schema>}}
+
+{{<instance-pass `Instance with value present in the enum is valid`>}}
+true
+{{</instance-pass>}}
+
+{{<instance-fail `Instance with value not present in the enum is invalid`>}}
+{ "foo": "baz" }
+{{</instance-fail>}}
+-  _Without specifying a type, you can utilize enum to accept values of various types._
