How to create two dimensional array when I have an object in javascript?

Question

I have an object like this:

 const object = {name: ['Jim', 'Jack', 'Betty'],
                 age: [14, 15, 16],
                 gender: ['M', 'M', 'F']}

What I want is to create a text like that:

Jim   14   M
Jack  15   M
Betty 16   F

Answer 1

Try using map()

 const object = { name: ['Jim', 'Jack', 'Betty'], age: [14, 15, 16], gender: ['M', 'M', 'F'] } const transpose = (arr) => arr[0].map((_, colIndex) => arr.map(row => row[colIndex])); const transposed = transpose([object.name, object.age, object.gender]) const result = transposed.map(row => row.join('\\t')).join('\\n') console.log(result)

Answer 2

If you have a specific properties and have same length, this does the trick:

 const object = {name: ['Jim', 'Jack', 'Betty'], age: [14, 15, 16], gender: ['M', 'M', 'F']} const [names,ages,genders] = Object.values(object); const rows = names.map((name, i)=>[name, ages[i], genders[i]]); const result = rows.map(row => row.join('\\t')).join('\\n') console.log(result)
