This tutorial teaches us how to remove the options from a dropdown list using JavaScript. Usually, this is not frequent that users get the option to remove any option from the dropdown list but this is possible if the option is provided by the programmer. If the programmer wants to provide the option to remove the dropdown then in JavaScript it is possible with the help of the remove() method. Using the DOM user can select the option to remove and by providing a function it could be passed to the remove method which will remove it. Let’s look into ... Read More
In this tutorial, we will explore how we can remove leading zeroes from any number in JavaScript. JavaScript removes leading zeroes from an integer variable automatically, but this is not the case when we consider strings in JavaScript. It is possible that a string in JavaScript which represents a numerical value may contain leading zeroes. These leading zeroes may cause problems when we try to perform any operation on the numerical value the string represents. This is why we will explore the ways by which we can remove the leading zeroes from a number, expressed as a string in JavaScript. ... Read More
This tutorial will discuss how to write swift program to print numeric hourglass pattern. Numeric pattern is a sequence of numbers which is used to develop different patterns or shapes like pyramid, rectangle, cross, etc. These numeric patterns are generally used to understand or practice the program flow controls, also they are good for logical thinking. To create a numeric hourglass star pattern we can use any of the following methods − Using nested for loop Using init() Function Using stride Function Here we divide the numeric hourglass pattern in two portions upper half portion and ...
