将对象转换为数组打字稿

Question

I have an object

{0: "item A", 1: "item B", 2: "item C"}

How can I convert the object to become array like this

[{0: "item A", 1: "item B", 2: "item C"}]

For now I have tried Object.keys(obj) but it returns each element in my object to array.

Really needs help. Thank you for helping

Answer 1

Just use bracket.

 let obj = {0: "item A", 1: "item B", 2: "item C"} console.log([obj]);

Answer 2

Also, there's an specific Array function for this matter: Array.of :

 console.log ( Array.of ( 1 ) )

This is more functional-friendly:

 const pipe = funs => x => funs.reduce( ( r, fun ) => fun ( r ), x ) const append = x => array => [ ...array, x ] const sum = values => values.reduce ( ( r, value ) => value + r ) const result = pipe ( [ Array.of, append ( 2 ), sum ] ) ( 1 ) console.log ( result )
