you can use `delete store` to reset full store or `delete store.id` to reset id, or `context.set("store", undefined)` to reset the full store, or `context.set("store.id", undefined)` to reset id.  
e.g.

```auto
[{"id":"cac01e08e6b2795d","type":"inject","z":"aa4e304feff52ade","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"[\"ohm114\"]","payloadType":"json","x":200,"y":140,"wires":[["301be4b76ba7e422"]]},{"id":"301be4b76ba7e422","type":"function","z":"aa4e304feff52ade","name":"Store and foward","func":"let store = context.get('store') || {}\nif(msg.delete){\n delete store[msg.delete];\n}else{\nObject.assign (store, msg.payload)\n}\ncontext.set('store', store); \n\nmsg.payload = store;\nreturn msg;","outputs":1,"noerr":0,"initialize":"","finalize":"","libs":[],"x":410,"y":140,"wires":[["b729f09bd2d6ebe8"]]},{"id":"ca79c7ca4a9c4e5b","type":"inject","z":"aa4e304feff52ade","name":"","props":[{"p":"payload.id","v":"[\"axc123\"]","vt":"json"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payloadType":"str","x":190,"y":180,"wires":[["301be4b76ba7e422"]]},{"id":"b17d678a.cb8418","type":"inject","z":"aa4e304feff52ade","name":"delete id","props":[{"p":"delete","v":"id","vt":"str"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","x":190,"y":260,"wires":[["301be4b76ba7e422"]]},{"id":"bfe9d959.0f4958","type":"inject","z":"aa4e304feff52ade","name":"delete 0","props":[{"p":"delete","v":"0","vt":"str"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","x":200,"y":300,"wires":[["301be4b76ba7e422"]]},{"id":"b729f09bd2d6ebe8","type":"debug","z":"aa4e304feff52ade","name":"debug 2","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","statusVal":"","statusType":"auto","x":620,"y":140,"wires":[]}]
