javascript/typescript utility library

/**
 * Creates a function that iterates over `pairs` and invokes the corresponding
 * function of the first predicate to return truthy. The predicate-function
 * pairs are invoked with the `this` binding and arguments of the created
 * function.
 *
 * @since 5.12.0
 * @category Util
 * @param pairs The predicate-function pairs.
 * @returns Returns the new composite function.
 * @example
 *
 * ```js
 * const func = cond([
 *   [matches({ 'a': 1 }),         () => 'matches A'],
 *   [conforms({ 'b': isNumber }), () => 'matches B'],
 *   [() => true,                  () => 'no match']
 * ])
 *
 * func({ 'a': 1, 'b': 2 })
 * // => 'matches A'
 *
 * func({ 'a': 0, 'b': 1 })
 * // => 'matches B'
 *
 * func({ 'a': '1', 'b': '2' })
 * // => 'no match'
 * ```
