In this tutorial, we will learn how to preserve leading 0 with JavaScript numbers. Sometimes we need to sort strings that are similar to numbers. For example, 10 comes before 2, but after 02 in the alphabet. Leading zeros are used to align numbers in ascending order with alphabetical order. Following are the methods used to preserve leading zero with JavaScript numbers. Using the Number as a String The number is converted into a string using string manipulation, and the leading zero is preserved. Syntax myFunc2('Neel', 27, '0165') The function myFunc2() is called, and the values are passed ... Read More
This tutorial will discuss how to write swift program to check the dictionary is empty. A dictionary is used to store data in the form of key-value pair in the collation without any defined-order. Here the type of the keys are same as well as the type of the values are also same. Each key is behave like an identifier for the associate value inside the dictionary and each value has a unique key. Swift dictionary is just like the real dictionary. It loop up values according to their identifier. Syntax Following is the syntax for creating dictionary − var ... Read More

This tutorial will discuss how to write Swift program to display Armstrong numbers between intervals using function The sum of nth power of individual digit of a number is equal to the number itself, then such type of number is known as Armstrong number. Suppose we have a number 407 so here n = 3 407 = 43 + 03 + 73 407 = 64 + 0 +343 407 = 407 Hence 407 is Armstrong number Suppose we have another number 2346, so here n = 4 2346 = 24 + 34 + 44 + 64 2346 = 16 + ...

In this tutorial, we will learn how to pass the value 'undefined' to a function with multiple parameters in JavaScript. In JavaScript, the data type of 'undefined' is primitive. When a variable is declared, JavaScript automatically assigns the value 'undefined' to it. If a function has multiple parameters and one of the parameters' values is not available at the moment, then we need to omit that parameter's value from the function call. But if we omit the parameter's value with a blank space, the JavaScript will show an error. Syntax function abc(param1, param2, param3) { console.log(param1, ... Read More
This tutorial will discuss how to write swift program to check Armstrong number. The sum of nth power of individual digit of a number is equal to the number itself, then such type of number is known as Armstrong number. Suppose we have a number 407 so here n = 3 153 = 13 + 53 + 33 153 = 1 + 125 + 27 153 = 153 Hence 153 is Armstrong number Suppose we have another number 8973, so here n = 4 8973 = 84 + 94 + 74 + 34 8973 = 4096 + 6561 + 2401 ...

This tutorial will discuss how to write swift program to display Armstrong number between two intervals. The sum of nth power of individual digit of a number is equal to the number itself, then such type of number is known as Armstrong number. Suppose we have a number 407 so here n = 3 407 = 43 + 03 + 73 407 = 64 + 0 +343 407 =407 Hence 407 is Armstrong number Suppose we have another number 2346, so here n = 4 2346 = 24 + 34 + 44 + 64 2346 = 16 + 81 + ...

To manipulate JavaScript’s Date object, you can either use get or set method and properties. For example, to set hours or to get minutes in JavaScript. Once a Date object is created, a number of methods allow you to operate on it. Most methods simply allow you to get and set the year, month, day, hour, minute, second, and millisecond fields of the object, using either local time or UTC (universal, or GMT) time. Here is a list of the methods used to Date and their description. Sr.No Methods & Description 1 date() Returns today's date ... Read More
This tutorial will discuss how to write swift program to find the geometric mean of the numbers. Geometric mean also known as GM. Geometric mean is defined as the xth root of the product of x numbers. Suppose we have x elements(that are, a1, a2, a3, ....ax) in the given array, then the geometric mean is − GM = (a1 * a2 * a3 * a4 * ....*ax)1/x Below is a demonstration of the same − Input Suppose our given input is − MyVal = [34, 67, 2, 45, 8, 12] Output The desired output would be − Geometric ...

This tutorial will discuss how to write swift program to find the harmonic mean of the numbers. Harmonic mean also known as HM is defined as the reciprocal of the average of reciprocal. Or we can say that harmonic mean is the reciprocal of the arithmetic mean by their reciprocal. Suppose a1, a2, a3, a4, .....an are the n-elements of a collection then the harmonic means is − HM = n/[(1/a1) + 1/(a2) + 1/(a3) + 1/(a4)+...+ 1/(an)] Below is a demonstration of the same − Input Suppose our given input is − MyVal = [3.4, 1.2, 7.8, 4.5, 2.4] ...
