I recently created a JavaScript code snippet that looks like this:
let var1 = 1;
window.var2 = 2;
After running the code in the Chrome console, I entered window to inspect the global window object. Surprisingly, only the second variable appeared and the first one was nowhere to be found. This confused me as I expected both variables to be part of the global window object.
Could someone explain why this is happening?
Both variables can be found within the windows object:
var variable1 = 1;
window.variable2 = 2;
console.log(Object.keys(window).filter(key=>key.substr(0,3)=='var'));The output will show:
[
"variable1",
"variable2"
]
After further exploration, it appears that the issue stemmed from placing the type="module" attribute within the script tag. Once I removed it, I successfully accessed it on the global window object.
<script type="module" src="js/app.js"></script>
