how to create json object in angular2

Question

i want to create J SON object in angular2 like this:

{ "classifications": [ 
                      { "type1" : [{"name":"text"},{"name":"text2"},{"name":"text2"}]} , 
                      { "type2" : [{"name":"image"},{"name":"img2"},{"name":"img3"},{"name":"img4"}]} ,
                      { "type3" : [{"name":"mp3"}]}
                      ] 
        }

is this the right way or not?? if not then how to make it and how to get data from this J SON object??

You don't need the " for the keys but besides that it should be fine. — Günter Zöchbauer

let x = { "classifications": [ 
                      { "type1" : [{"name":"text"},{"name":"text2"},{"name":"text2"}]} , 
                      { "type2" : [{"name":"image"},{"name":"img2"},{"name":"img3"},{"name":"img4"}]} ,
                      { "type3" : [{"name":"mp3"}]}
                      ] 
        }

console.log(x.classifications[0].type1[0].name);

this make an error : Property 'type1' does not exist on type '{ "type1": { "name": string; }[]; } | { "type2": { "name": string; }[]; } | { "type3": { "name": ...'.

You can try console.log(x['classifications'][0]['type1'][0]['name']);
