"Return" cause of function break. Why?

Question

Im trying to understand something seemingly incredibly simple.

console.log(${key}: ${value}) - works so long as return below is commented out.
Once, the 'return' statement is included below it, the function doesn't work and only returns the first key-val of the list.
It returns: a: something

Why is it that console.log(${key}: ${value}) and Return (${key}: ${value}) can be so different and how can I reformat to output the full key/value list from the function? My expected result is: "a: somestring, b: 42,c: false"

Thanks!

   const object1 = {
    a: "somestring",
    b: 42,
    c: false,
   };

   const defineKeyValPairs = (data) => {
      console.log(data); //outputs: {a: 'some string', b: 42, c: false}
      for (const [key, value] of Object.entries(data)) {
        console.log(`${key}: ${value}`); // returns "a: somestring, b: 42,c: false" so long as return below is commented out
        // return `${key}: ${value}`; // doesn't work - returns "a: somestring"
    }
   };

   defineKeyValPairs(object1);

Thank you @Konrad, @epascarello and @Ivar for the direction.
Here's the solution:

const defineKeyValPairs = (data) => {
    console.log(data);
    return (Object.entries(data).map(([key, value]) => {
        return `${key}: ${value}`;
    }))
};

defineKeyValPairs(object1);

Returns: a: somestring, b: 42,c: false as the question requested. Hopefully this helps someone else out.
