使用 map 或 reduce 将数组转换为记录

Question

I have this 2d array.

[["hair",4560],["ringtones",33]]

I would like to know how to convert it to record with reduce or map:

[{id: {product:"hair"}, price: [454]}, {id: {product:"ringtones"}, price: [6000]}] 

I want to use it to know in each row how col is longest.

thanks

You can easily use an array map that loops through each item in the array and parses it.

let array = [["hair",4560],["ringtones",33]];
let arrayOfObjects = array.map(e => {
    // The structure as recommended in the comments
    // If you want the nested structure you originally were wondering about,
    // you can change the return line to match that structure
    return {product: e[0], price: e[1]};
});

/**
    Contents of the arrayOfObjects is:
    [
        { product: 'hair', price: 4560 },
        { product: 'ringtones', price: 33 }
    ]
