A very good W3school tutorial can be found here.

Javascript – JS object change String to Number

I have a problem. I have an abject

let aa = [
    {"x":"1","y":"12"},
    {"x":"2","y":"12"},
    {"x":"3","y":"12"},
    {"x":"4","y":"25"},
    {"x":"5","y":"45"},
    {"x":"6","y":"49"}
]

but I need an object like this

let aa = [
    {"x": 1,"y": 12 },
    {"x": 2,"y": 12},
    {"x": 3,"y": 12},
    {"x": 4,"y": 25},
    {"x": 5,"y": 45},
    {"x": 6,"y": 49}
]

I try to use

Object.keys(a).forEach(function(el){
  i[el] = parseInt(i[el])
 
})
}

but it didn`t help me

    You could map the entries with a new type.

    let aa = [
    {"x":"1","y":"12"},
    {"x":"2","y":"12"},
    {"x":"3","y":"12"},
    {"x":"4","y":"25"},
    {"x":"5","y":"45"},
    {"x":"6","y":"49"}
],
    result = aa.map(o => Object.fromEntries(Object.entries(o).map(([k, v]) => [k, +v])));

console.log(result);

    const aa = [
    {"x":"1","y":"12"},
    {"x":"2","y":"12"},
    {"x":"3","y":"12"},
    {"x":"4","y":"25"},
    {"x":"5","y":"45"},
    {"x":"6","y":"49"}
]

const ab = aa.map(a => ({ x: Number(a.x), y: Number(a.y)}))

    That will do the job if all the strings are indeed correct numbers, otherwise you have to handle errors somehow.
