I have a JSON object as follows. After sending ajax call I want to clear this. How I can do?

```
var cfamFwdDtls = {
    cndtwizid: [],
    clientIdsInstnIds: [],
    positioncd: '',
    positionCnt: '',
    rcrtrInstnId: '',
    positionLocation: {
        cntryIdFrCndt: '',
        stateIdFrCndt: '',
        zipIdFrCndt: '',
        cityIdFrCndt: ''
    },
    searchPstnSkill: []
};

```
