convert_an_array_of_strings_to_array_of_numbers.js

// Description:
// Oh no!
// Some really funny web dev gave you a sequence of numbers from his API response as an sequence of strings!
// You need to cast the whole array to the correct type.
// Create the function that takes as a parameter a sequence of numbers represented as strings and outputs a sequence of numbers.
// ie:["1", "2", "3"] to [1, 2, 3]
// Note that you can receive floats as well.

// SOLUTION:

function toNumberArray(stringarray) {
    for (let i = 0; i < stringarray.length; i++) {
        stringarray[i] = +stringarray[i];
    };
    return stringarray
}

// SOLUTION 2:

const toNumberArray = stringarray => {
    return stringarray.map(el => +el)
}
