Let's look at an example. There are several built-in ways to find a minimum or maximum value from an array in JavaScript, including using the Math functions with the spread operator () and sorting the array numerically with .sort(). Simple and elegant. Most of the time it happens when interviewer ask a developer that, tries to implement the same thing without using any inbuilt function because it might happen that the function like Math.max() and Math.min() not available on another technology stack. Returns the value of the first element in an array that pass a test. If the function is not in strict mode, null and undefined will be replaced with the global object, and primitive values will be converted to objects. Contribute your expertise and make a difference in the GeeksforGeeks portal. Quoting MDN: The find() method returns the value of the first element in the provided array that satisfies the provided testing function.

This invokes the constructor function as a plain function, which means new.target is undefined, and classes throw an error because they can't be called without new. Using reduce() we check to see if the current Y value of the array is less than the minimum value stored in the reduce() function. Thank you!

The static function Math.min() returns the lowest-valued number passed into it, or NaN if any parameter isn't a number and can't be converted into one. The problem with Math.min() is it expects each parameter to be input separately and cannot take an array of multiple numbers as input. The Math.min () static method returns the smallest of the numbers given as input parameters, or Infinity if there are no parameters.
