如何在一行中创建 Typescript 中的对象列表

Question

I have a list of values

let values = ["value-01", "value-02"]

I go ahead and turn them into the list of objects:

let result = [];
for (let each of values) { 
  result.push({ value: each });    
};

console.log(result)

which logs

[ { value: 'value-01' }, { value: 'value-02' } ]

I wonder if there is a shorter way to achieve this? In Python I could do it in a single line like so:

result = [{"value": each} for each in values]

Answer 1

It's a pretty simple mapping.

 let values = ["value-01", "value-02"]; const result = values.map(value => ({ value })); console.log(result);

Answer 2

While there is nothing wrong with using a for loop, you could make use of this code using map() , split() and computed property names:

 let values = ["value-01", "value-02"]; let ans = values.map((a) => ({ [a.split('-')[0]] : a })) console.log(ans);
