    const objArr = [
        {prop1: 'value1', prop2: 'value11'},
        {prop1: 'value2', prop2: 'value22'},
        {prop1: 'value3', prop2: 'option33'},
        {prop1: 'value4', prop2: 'option44'}
    ]

    const newObjArr = objArr.map(obj => {
            if (['value1', 'value2'].includes(obj.prop1)) {
                return {...obj, prop1: 'newValue'}
            }
            return obj
        }
    )
    
    // const responseGotten = [
    //     { prop1: 'newValue', prop2: 'value11' },
    //     { prop1: 'newValue', prop2: 'value22' },
    //     { prop1: 'value3', prop2: 'option33' },
    //     { prop1: 'value4', prop2: 'option44' }
    // ]
