How does one fetch some JSON data and save it into a variable and not continue executing the rest of the script until the fetch api has fetch the JSON data?

Here is my code which will return undefined in the console.

var myVar;

fetch("myFile.json")
	.then(res => res.json())
	.then(data => {
	myVar = data;
});
	
console.log(myVar)

//rest of code executes...
