Using jq, convert array of objects to object with named keys

Given a json file in the format as :

[ {  name : "A",  value : "1" }, {  name : "B",  value : "5" }, {  name : "E",  value : "8" }]

How would I convert it to something like this using jq:

{"A" : {   name : "A",   value : "1" },"B" : {  name : "B",  value : "5" },"E" : {  name : "E",  value : "8" }}

jq '{(.[].name) : "the name"}''myfile.json' gets me an object with [].name keys but how do I assign the object to it?
