Re-writing a JavaScript ternary block

How do I rewrite a JavaScript ternary line inside this code: 

    // Change the target user
    const typeaheadOptions = {
        selector: '#user',
        name: 'userTypeahead',
        display: 'NAME',
        ajaxURL: '/index.cfm?',
        qryParams: [{
            name: 'fuseaction',
            value: 'main.getJSON',
            prefetch: true,
            remote: true,
        }, {
            name: 'isJSON',
            value: true,
            prefetch: true,
            remote: true,
        }, {
            name: 'qName',
            value: 'getUsers',
            prefetch: true,
            remote: true,
        }, {
            name: 'name',
            value: '%QUERY',
            prefetch: false,
            remote: true,
        }],
        wildCardParam: '%QUERY',
        id: 'NAMECODE',
        limit: 150,
        templates: {
            suggestion: "<div>{{NAME}}</div>"
        },
        events: [{
            eventType: 'select',
            callback: function(ev, suggestion) {
                iptws.unsubscribe('iptdeadlines.' + caseModel.activeItem.NAMECODE());
                caseModel.activeItem.NAMECODE(suggestion.NAMECODE);
                iptws.subscribe('iptdeadlines.' + caseModel.activeItem.NAMECODE());
                const params = {
                    fuseaction: 'main.getJSON',
                    isJSON: true,
                    qName: (caseModel.currentData() === 'daily') ? 'getUserDeadlines' : 'getWeeklyDeadlines',
                    namecode: suggestion.NAMECODE,
                };
                $.when(
                    $.ajax({
                        method: 'GET',
                        url: '/index.cfm',
                        data: params
                    }),
... 

Select allOpen in new window

I tried adding this before the line "// Change target user" : 

    let whatQuery;
    if(caseModel.currentData() === 'daily'){
        whatQuery = 'getUserDeadlines'
    } else if (caseModel.currentData() === 'weekly') {
        whatQuery = 'getWeeklyDeadlines'
    } else {
        whatQuery = 'getCustomDeadlines' 
    }

Select allOpen in new window

Then I replaced the bolded ternary code with this line: 

                    qName: whatQuery,

Select allOpen in new window

But that did not work. JS complained about the '{' character here:

=== 'daily'){

Select allOpen in new window

So it looks like changing the ternary line with if statements is not working at that location. How can I change the ternary code and use if statements instead?
