javascript - How can I specify an array of objects indexed by a field in Typescript? -

-

i have got far:

testquestions: {     data: [{ admintestid: number,              admintestquestionid: number,              questionuid: string,              subtopidid: number,              title: string }] };

now add in object called datamap. object result of passing data through reduce function:

 testquestions.datamap = data.reduce((rv, v) => {             rv[v.questionuid] = v;             return rv;         }, {});

can telling me how can define (inline) datamap?

testquestions: {     data: [{ admintestid: number,              admintestquestionid: number,              questionuid: string,              subtopidid: number,              title: string }],    datamap: questionuid: string [{ admintestid: number,              admintestquestionid: number,              questionuid: string,              subtopidid: number,              title: string }]

};

i have tried above it's not correct. hope can here.

you close. first lets break out object type own interface clarity.

interface question {     admintestid: number;      admintestquestionid: number;      questionuid: string;      subtopidid: number;      title: string; }

this syntax looking in datamap.

interface questionmap {     [questionuid: string]: question; }

all together.

interface testquestions {      data: question[];     datamap: questionmap; }  var testquestions: testquestions = {     data: [],     datamap: {}, };
