JavaScript Mastery from Zero to Hero - Prepare for Coding Interviews - How to Return the Smallest Number in Nested Array

This video tutorial introduces JavaScript algorithms focusing on nested and multidimensional arrays. It explains how to find the minimum value in sub-arrays using the Math.min method. A practical example demonstrates the use of Math.min with the spread operator. The lesson concludes with an exercise to create a function that returns the smallest numbers from each sub-array.

What is the primary goal when working with nested arrays in this lesson?

• To calculate the sum of integers in each sub-array

• To return the lowest integer in each sub-array

• To sort the integers in each sub-array

• To find the highest integer in each sub-array

Which JavaScript method is used to find the minimum value in an array?

• Math.max

• Math.min

• Array.min

• Array.max

What operator is used in conjunction with Math.min to handle arrays?

• The rest operator

• The spread operator

• The increment operator

• The decrement operator

What is the task of the function 'smallestNumbers' in the exercise?

• To calculate the average of each sub-array

• To sort each sub-array in ascending order

• To return the smallest numbers from each sub-array

• To return the largest numbers from each sub-array

Where should you share your solution for the exercise?

• In the Discord channel

• In a private message to the instructor
