In this article, you will understand how many numbers in the given array are less/equal to the given value using the percentile formula. We calculate the percentage of numbers in the given array less or equal to the number using the formula − Percentile = (n/N) * 100 Where, n is the number of values below x and N is the total number of values. Example 1 In this example, we use a for-loop to iterate the array and check each element whether the value is less, equal or greater than the given input value. const calculationPercentile = ...

In this article, you will understand how ES6 (ES2015) evolved and brought new features to modern day JavaScript. ES6 stands for ECMAScript 6. It is the 6th version of ECMAScript and was created to standardize the JavaScript. The top 10 features of ES6 are: let and const keywords, Arrow Functions, Multi-line Strings, Default Parameters, Template Literals, Destructuring Assignment, Enhanced Object Literals, Promises. Example 1 In this example, let’s demonstrate the Arrow function(=>) − console.log("An Arrow function Square has been defined") square = (x) => { return x * x; } let inputValue = 6 console.log("The input ...

The chart is very important to visualize the data, and we can show the data in various formats and analyze the pattern in the data. Also, the chart is more important for data scientists as they need to analyze the various data. Bootstrap is a library that allows us to draw various charts using JavaScript or JQuery. It contains the functions that we need to import and pass chart type and chart data as an argument of the function, and it will prepare a chart for us. This tutorial will teach us to draw various chart patterns using Bootstrap. Syntax ... Read More
In this article, you will understand how Promise.any() method differs from Promise.race() method in JavaScript. The Promise.any() method in javascript is one among promise concurrency methods. It is useful when the first task needs to be completed. The Promise.race() method in javascript is one among promise concurrency methods. It is useful when the first async task need to be complete, but do not care about its eventual state (i.e. it can either succeed or fail). Example 1 In this example, let’s look at how the Promise.any() method works console.log("Defining three promise values: promise1, promise2 and promise3"); const promise1 = ... Read More
In this article, you will understand how to check if the object value exists, if not, add a new object to the array using JavaScript. In Javascript, almost every variable is an object. An object can be a string, numbers, boolean values, etc. They can also be key-value pairs. An array in javascript is a special variable that can hold more than one item. An array can be initialized using the keyword ‘const’. Example 1 In this example, we check the existence of the object using the .some() function. var inputArray = [{ id: 1, name: "JavaScript" }, ...

In this article, you will understand how implicit coercion differs from Explicit coercion in JavaScript. An implicit coercion is an automatic conversion of values from one datatype to another. It is also known as type conversion. An explicit coercion is the conversion of data type depending on the user's necessity. Example 1 In this example, let us learn about implicit coercion. let inputValue = "5" console.log("The input variable is defined as: ") console.log(inputValue, typeof inputValue); let resultValue = Number(inputValue); console.log("The input variable is defined as: ") console.log(resultValue, typeof resultValue); Explanation Step 1 −Define a variable: inputValue and assign ...

In this article, you will understand how internationalization works in JavaScript. Internationalization is the process of preparing software so that it can support local languages and cultural settings. It can include changing the date and time format, changing the metric system format, language format, etc. Example 1 In this example, let’s understand the changing of date and time formats. var inputDate = new Date(1990, 2, 25); console.log("The date is defined as: ") console.log(inputDate) console.log("The date in United Kingdom format is: ") console.log(new Intl.DateTimeFormat('en-GB').format(inputDate)); console.log("The date in American format is: ") console.log(new Intl.DateTimeFormat('en-US').format(inputDate)); Explanation Step 1 − Define ...

In this article, you will understand how does Promise.all() method differs from the Promise.allSettled() method in JavaScript. The Promise.all() method takes in one or multiple promises as input and returns a single Promise. This returned promise fulfills when all of the input's promises are fulfilled. It rejects a promise when any of the input's promises is rejected, with this first rejection reason. The Promise.allSettled() method takes in one or multiple promises as input and returns a single Promise. This returned promise fulfills when all of the input's promises settle (including when an empty iterable is passed), with an array of ... Read More
