Throughout this video, we will explore various interview questions related to the filter() function. We will cover topics such as:
Q1 : Given an array of numbers, use the filter method to create a new array that contains only the even numbers.
Q2 : Write a code snippet using the filter method to extract all the positive numbers from an array.
Q3 : How can you use the filter method to find all the words in an array that have more than 5 characters?
Q4 : Given an array of objects, use the filter method to create a new array that contains only the objects with a specific property value.
Q5 : Write a function that takes an array of strings and uses the filter method to find all the strings that start with a specific letter.
