Then using the JavaScript iteration method this can be easily done.Let’s see various ways in JavaScript to create ... Read More
In this tutorial, we will check if two numbers are approximately equal or not. In case given two numbers are equal then we will print yes, it is otherwise not it’s not.But let me make you clear that we are not going to do any magic here, basically we will also have to give an epsilon value.So, when we calculate the absolute difference between those two numbers and then compare with the epsilon then if absolute difference is lesser than the epsilon then the numbers are approximately equal else not approximately equal.Suppose two numbers given is 6.79 and 6.75 and ...

In this tutorial, we will check if the bottom part of a page is visible or not to the user. We can do this functionality by using the height of the window and the height of the scrolled window.

Both MapReduce and Spark are examples of so-called frameworks because they make it possible to construct flagship products in the field of big data analytics. The Apache Software Foundation is responsible for maintaining these frameworks as open-source projects.MapReduce, also known as Hadoop MapReduce, is a framework that enables application writing, which in turn enables the processing of vast amounts of data on clusters in a distributed form while maintaining fault tolerance and reliability. The MapReduce model is constructed by separating the term "MapReduce" into its component parts, "Map, " which refers to the activity that must come first in the ... Read More
