Get the smallest number from an array of numbers using JavaScript?

A solution in one line of code:

array.sort()[0]

It first sorts the array from smallest to largest:

array.sort()

This puts the smallest item in the first index position, which is retrieved like this:

array[0]

Using Math.min with rest parameters:

Math.min(...array)

You can loop through each value in the array and return the smallest one:

var array = [54, 322, 12, 24, 143, 343.32, 34.1]

var minValue = array[0]

for (var i=0; i < array.length; i++) {
  if (array[i] < minValue) {
    minValue = array[i]
  }
}

// minValue = 12

Math.min.apply(Math, array)
