range-within - Check that one range is entirely contained within another range

Checks that one range of numbers, like [1, 5] is enirely contained within another range of numbers, like [0, 10].

Usage

The function takes two arguments, each of which is an object containing the start and end properties, which must be numbers.

The order of the ranges doesn't matter; you can put the larger or the shorter range first.

const within = require('range-within');

let range1 = {start: 1, end: 10};
let range2 = {start: 5, end: 10};

let result = within(range1, range2); // returns true
