The Underscore.js is a JavaScript library that provides a lot of useful functions that help in programming in a big way like the map, filter, invokes, etc even without using any built-in objects. The _.max() function is used to find the minimum element from the list passed. If an iterate is given, then it will be applied to each value and generate criteria to rank the values and find the minimum element....
