在 JavaScript (ES6) 中将数组的每个元素转换为单独的数组

Question

Convert each element of array into separate array and push into one array.

inputArray = ['One', 'Two', 'Three']

Required Output

outputArray = [['One'],['Two'],['Three']]

By using ES6 how to get this output?

Answer 1

You an use array.map to do that:

 const inputArray = ['One', 'Two', 'Three']; const result = inputArray.map(x => [x]); console.log(result);

Answer 2

You mean a simple map of each element? That can be done very quickly like so

const outputArray = inputArray.map(el => [el]);
