I'm having a really hard time getting started on these four functions can someone please help me? Javascript please!
There is comments on what the functions have to do. Can someone please implement the four functions?
The front end will be developed using HTML and Javascript and the back end is built using Node.js framework.
The back end is a REST service with four functions.
31 32 33 34 35 app.get('/contents', (request, response) => { // TODO: this function should return the list of the themes of the dictionary // Each these has an id and a name. The id is a number. Each theme has a unique id. // This function should return a json string. }); 36 37 40 41 app.get('/pages/:contentId', (request, response) => { // TODO: this function should return the list of the ids of // the images that are associated with the theme whose id is equal to contentId. // Each image has an id and a name.
