Use if and else to make judgments, but this code is really too redundant, please help optimize it

this is a piece of code I wrote, which uses a lot of if and esle, but I feel unable to optimize it myself

how can I optimize without es6?

const actions = new Map([ ['guest_1', ()=>{/*do sth*/}], ['guest_2', ()=>{/*do sth*/}], ['master_1', ()=>{/*do sth*/}], ['master_2', ()=>{/*do sth*/}], ['default', ()=>{/*do sth*/}], ]) const onButtonClick = (identity,status)=>{ let action = actions.get(`${identity}_${status}`) || actions.get('default') action.call(this) }
