Hi! This is my first post so I hope I don’t just ask something redundant. I’m currently working through the “Re-creating the Lodash Library” module: (https://www.codecademy.com/paths/web-development/tracks/web-dev-js-arrays-loops-objects/modules/pjs-javascript-capstone/projects/lodash)
I’m on Step 23, where I am trying to implement the invert method, but I’m getting a Error. Here is my code for the method:
const _ = {
invert(obj) {
let arr = [];
for (const [key, value] of Object.entries(obj)) {
arr.push([value, key]);
}
return Object.fromEntries(arr);
},
};
When I try to run the test, I get an Error as follows:
/home/ccuser/workspace/underscore-javascript-capstone/_.js:47
return Object.fromEntries(arr);
^
TypeError: Object.fromEntries is not a function

I’m wondering if this is a quirk with the Node.js version, or if I’m doing something wrong. I tried my code in another online JavaScript playground and it seemed to work. Any advice?
