Map it to the Number function:
var array = ["1", "2", "3", "4", "5"];
array = array.map(Number);
array; // [1, 2, 3, 4, 5]

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);

good answer, but whats the point of the snippet which expands to nothing ?

@amdixon Just open the console (F12) of your browser ;)

point taken - it is just slightly faster than copy+pasting it into the console ;)

The unary plus converts things into a number, just like the unary minus converts it into a number and negates it.
