sortByProperty(
      property: string,
      objects: object[]
): void

Re-orders objects, sorted by property in each.
Based on the data type of objects[0][property], it decides how to sort all objects.
That type must be either number, string, or boolean. Sorting is done either numerically or
alphabetically (booleans are treated as strings).

Note: property is a string that can include dot notation ( i.e.,
'property.subproperty.subsubproperty' ).
Note: even if property is an array index, here you need to use dot-notation
and not square braces, i.e., '1.0' // instead of [1][0]

Examples

let objects = [
    {user: {email: '[e-mail]', age: 55}},
    {user: {email: '[e-mail]', age: 83}},
    {user: {email: '[e-mail]', age: 19}},
    {user: {email: '[e-mail]', age: 28}}
];
sortByProperty('user.email', objects);
console.log(objects);

// If the property is undefined in the first object, this triggers error:
objects = [
    { email: '[e-mail]'},
    { email: '[e-mail]', age: 28 },
    { email: '[e-mail]', age: 55 } 
];
sortByProperty('age', objects);
// Console: "Error: The first object in the objects array either doesn't have the specified
//      property, or that property doesn't have a value."


// The following is something you need to be careful with.
// We're going to sort by 'user.age', but the value in first object will be a string,
// meaning sorting will be alphabetical:

objects = [
    {user: {email: '[e-mail]', age: '10'}}, // string means sorting will be alphabetical.
    {user: {email: '[e-mail]', age: 55}},
    {user: {email: '[e-mail]', age: 100}},
    {user: {email: '[e-mail]', age: 20}},
