create variable by matching variable value to object value?

Question

I'm attempting to create a variable that contains the value of an object. the variable eventDateValue below is what i'm struggling with. I'm trying to match the value of EventName to the object events2020 and if there's a match (must match the object name) pass the value of that match to the variable eventDateValue.

below is my code

function getPage(){
    let pageActual = window.location.href;
    console.log(pageActual);

    let pageName = /127(.*)/;
    let EventName = pageName.exec(pageActual);
    console.log(EventName[1]);

    const events2020 = {
        Event1 :'February 19, 2020',
        Event2 :'February 18, 2020',
        Event3 :'February 17, 2020',
        Event4 :'February 16, 2020',
        Event5 :'February 15, 2020',
        Event6 :'February 14, 2020'
    };

    let eventDateValue = Object.keys(events2020)

    [Object.values(events2020).indexOf(EventName)] 

    console.log(eventDateValue);
}

Object.keys gives you an array of keys, not a single value. Also, what is that [.....] line supposed to do? — Mike 'Pomax' Kamermans

I think what you need is let eventDateValue = events2020[EventName]

Let me add some context, I'm writing a script that fires off an event based on the event date . It looks at the current date and compares it to the day the event starts. If it matches it triggers a CSS change. I have over 154 events in total so I'm trying to automate this. I wrote a function that essentially takes the current page address after the' .com ' and creates an event name. Example : event.com/eventname. It stores this in a variable. Im now attempting to match the event name to one of the events in my events object in order for the browser to determine the current date for the event
