+## Remove property
+
+Remove property from a JSON array of objects:
+
+```json
+{
+  "member_inputs": [
+    {
+      "name": "Thomas",
+      "input_type": "select"
+    },
+    {
+      "name": "Martha",
+      "input_type": "text"
+    }
+  ]
+}
+```
+
+```sh
+jq '.member_details |= map(del(.input_type))' memberDetails.json
+```
+
+> Add '-i' to modify the source file directly (in-place)
+
+> Multiple properties can be deleted simply by chaining,
+> e.g.`(del(.input_type, .another_property))`
