# Getting the largest number from an array

Posted on January 4, 2021

`Math.max()` returns the largest of zero or more numbers passed to it. We can use the spread operator when passing an array to get the largest number from that array.

``````// get the largest number from a list of numbers
Math.max(69, 420, 108, 47)  // ⇒ 420

// passing an array instead of individual numbers returns `NaN`
const numbers = [69, 420, 108, 47]
Math.max(numbers)           // ⇒ NaN

// we get the expected result by spreading the array
const numbers = [69, 420, 108, 47]
Math.max(...numbers)        // ⇒ 420``````
``````// get the largest number from a list of numbers
Math.max(69, 420, 108, 47)  // ⇒ 420

// passing an array instead of individual numbers returns `NaN`
const numbers = [69, 420, 108, 47]
Math.max(numbers)           // ⇒ NaN

// we get the expected result by spreading the array
const numbers = [69, 420, 108, 47]
Math.max(...numbers)        // ⇒ 420``````

The same works for `Math.min()`.

``````// get the smallest number from a list of numbers
Math.min(69, 420, 108, 47)  // ⇒ 47

// passing an array instead of individual numbers returns `NaN`
const numbers = [69, 420, 108, 47]
Math.min(numbers)           // ⇒ NaN

// we get the expected result by spreading the array
const numbers = [69, 420, 108, 47]
Math.min(...numbers)        // ⇒ 47``````
``````// get the smallest number from a list of numbers
Math.min(69, 420, 108, 47)  // ⇒ 47

// passing an array instead of individual numbers returns `NaN`
const numbers = [69, 420, 108, 47]
Math.min(numbers)           // ⇒ NaN

// we get the expected result by spreading the array
const numbers = [69, 420, 108, 47]
Math.min(...numbers)        // ⇒ 47``````

## Splitting strings

When splitting strings, the sequence of characters we split at does not appear in the result. We can get all letters by splitting at the empty string.

## Splitting arrays into X elements and “the rest”

When a feature calls for the first five photos from a list and a link that says “27 more photos”, we can split the list into these two blocks.

## Composing functions to run in sequence

We can chain many functions together into a single function. That new function takes one input and runs it through its individual functions one by one.

## Inverting Boolean functions

We can create a helper function that makes functions return their Boolean opposite. This can be useful in the shorthand syntax for array methods.

## Mapping over objects

With this helper function, we can map over objects and change each of their values like we would do with arrays.
