// Replaces {n} in a string with the nth following parameter.
const format = (text, ...values) => text.replace(/{([0-9]*)}/g, (m, i) => values[i] || m)

// Example 1
console.log(format('Hello {0}! How\'s your {1}?', 'my dear', 'day been'))
// Output: Hello my dear! How's your day been?

// Example 2
const list = ['the city', 'train', 'speed', 'convenient']

/**
 * Converts an array to an array of n-tuples of its elements.
 * 
 * To generate a gap between the n-tuples a stride can be set. The stride is
 * offsetting the starting elements in the derived n-tuples.
 * 
 *   span = 3 and stride = 2
 *   [1,2,3,4,5,6,7] -> [[1,2,3], [3,4,5], [5,6,7]]
 * 
 *   span = 2 and stride = 3
