Quickest Way to get the Maximum Value of an Array of Numbers (Typed or Untyped)
npm install fast-max
npm install fast-max
why is it so much faster?
This library excels with typed arrays. It takes into account the theoretical maximum of a typed array.
For example, if you have a Uint8Array, it's not possible for a maximum value to be greater than 255,
so if we encounter a 255 in the array, we can stop searching for a higher value.usage
getting maximum value of a normal array
javascript
const fastMax = require("fast-max"); // or import max from "fast-max";const result = fastMax([0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]);
// result is 10
`getting maximum value of a typed array
javascript
const fastMax = require("fast-max");const pixel_values = Uint8Array.from([0, 128, 255, 34, ...]);
const result = fastMax(pixel_values);
// result is 255
`setting theoretical maximum
If you know that an array's values can't exceed a specific number,
you can set the theoretical_max.
javascript
const fastMax = require("fast-max");const numbers = [0, 9, 4, 2, 10, ...]);
const result = fastMax(numbers, { theoretical_max: 10 });
// result is 10
`no data value
If you want to ignore one or more specific values, you can set the no_data value.
javascript
const fastMax = require("fast-max");const numbers = [99, 0, 7, 99, 5, ...];
const result = fastMax(numbers, { no_data: 99 });
// result is 7
const result = fastMax(numbers, { no_data: [7, 99] });
// result is still 5
