Subject: [PATCH] refactor(core): simplify `concatStringsWithSpace` (#59820)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The new version of the function is smaller, eliminating extra bytes. The refactor improves both code size and readability while optimizing the implementation. Benchmark results for the old and new implementations are as follows:

```
concatStringsWithSpace_old x 149,225,311 ops/sec ±8.54% (50 runs sampled)
concatStringsWithSpace_new x 160,206,834 ops/sec ±5.72% (54 runs sampled)
```

Thus, the new implementation is both smaller and faster.
