This looks good. The format of the fr.js file scares me a bit as this file is something that will need to be edited by non-programmers. I assume this could be something where the messages.properties is the source of truth and we generate the translation files during bundling or something like that.

@jmiranda format of file can be simplified if it will cause troubles. I used this structure for navbar so i could easly generate menu dynamicaly. Further elements can be added to files with simpler - not nested structure and it should work too (as long as structure of both files - en and fr - will match). Example:
en = {
navbar: { nested as it is right now },
formStep1: {
field1: 'field1 in eng',
field2: 'field2 in eng',
}
...
}
