/** |
| 27 |
* The purpose of this function is to replace the requested translation file |
| 28 |
* with a file that contains all the translations for specific scripts. |
| 29 |
* |
| 30 |
* When developing a module and using Webpack's dynamic load feature, the script will be split into multiple chunks. |
| 31 |
* As a result, the WordPress translations expressions will also be split into multiple files. |
| 32 |
* Therefore, we replace the requested translation file with another file (generated in the build process) |
| 33 |
* that contains all the translations for the specific script (including dynamically loaded chunks). |
| 34 |
* |
