What is the difference between JS Map and JS Object?

I know that Map is hash table implementation for JS, but how does it differ from an object? With regards to how Python dictionaries work, there seems to be no difference.

const x = new Map();
x.set("foo", "bar");

const x = new Map();
x.set("foo", "bar");

const x = { foo: "bar" };

const x = { foo: "bar" };

Question about for loops

Why does the following code log numbers from 0 to 9 instead of 1 to 9? i is assigned as zero in the first expression, then it checks whether i is less than 10 and moves to the next expression which is i++, so it should increment the value of i to 1 instead and log it

for (let i = 0; i < 10; i++) {
    console.log(i);
}

for (let i = 0; i < 10; i++) {
    console.log(i);
}
