Hopw to store File.text() value outside of the promise [duplicate]

I want to parse the contents of a JSON file and store them in an object property data.current, outside of the promise used to read the file:

HTML

<form name="data">
    <label>
        <span>Load Data</span>
        <input type="file" accept="application/json">
    </label>
</form>

JavaScript

const data = {
    input: document.forms["data"].querySelector("input"),
    current: {}
}

data.input.addEventListener("change", function(event) {
    if(Object.entries(data.current).length == 0) {
        event.target.files[0].text()
            .then((content) => {
                data.current = JSON.parse(content);
                console.log(data.current)
            });
    console.log(data.current)
    }
});

Outputs

Line 11: Object { property1: [...], property2: [...], property3: [...] }

Line 13: Object { }

Expected Outputs

Line 11: Object { property1: [...], property2: [...], property3: [...] }

Line 13: Object { property1: [...], property2: [...], property3: [...] }

The first console.log(data.current) shows a parsed JSON Object, the second one an empty Object. How can I get the parsed JSON outside of the promise?
