The map() method creates a new array with the results of calling a provided function on every element in this array.

The unary + acts more like parseFloat since it also accepts decimals.

Refer this

Try this snippet:

var array = ["1", "2", "3", "4", "5"];
array = array.map(function(item) {
  return +item;
});
console.log(array);

Map it to the Number function:

var array = ["1", "2", "3", "4", "5"];
array = array.map(Number);
array; // [1, 2, 3, 4, 5]
