When line breaks should occur, they can be changed using the word-break property in CSS. Text line breaks typically only appear in specific locations, such as after a space or hyphen. Following is the syntax for word-break word-break: normal|break-all|keep-all|break-word|initial|inherit; Let’s dive into the article for getting better understanding on how can we prevent word breaking into different line in HTML table. Before that let’s have a quick view on the HTML table. HTML tables Web designers can organize information like text, images, links, and other tables into rows and columns of cells using HTML tables.

In this tutorial, we will learn to create an id using mongoose in JavaScript. Users can use the Mongoose NPM package in NodeJS to use MongoDB with NodeJS or connect MongoDB with the application. While storing the data in the MongoDB database, we must add a unique id to every data collection. However, if we don’t add an id, it generates automatically and adds to the data. Syntax Users can follow the syntax below to create an id using mongoose in JavaScript. var newId = new mongoose.mongo.ObjectId(); In the above syntax, we access the ‘mongo’ from the mongoose and ...

We can get the union of two arrays by merging both arrays and removing duplicate elements, and the union gives unique elements from both arrays. In this tutorial, we will learn to compute the union of JavaScript arrays using various approaches. Use the set() Data Structure The first approach is using the set() data structure. The set data structure can contain only unique elements. We can add all elements of both arrays into the set and create a new array from the set’s elements to create a union. Syntax Users can follow the syntax below to compute the union of ... Read More

Sometimes, it requires finding the total time elapsed while performing some operations in JavaScript. For example, we require to find the total time elapsed from users who have updated their profiles. Also, there can be other similar use cases where we need to find the difference between the particular time and the current time, finding the total time elapsed. Here, we will learn various approaches to finding the time elapsed in JavaScript. Using the Date() Object to find the time Elapsed in JavaScript In JavaScript, we can get the current time using the Date() object constructor. It returns the total ... Read More

In JavaScript, we can use the ‘&&’ operator to perform the AND operation between two elements and the ‘||’ operator to perform OR operation between two elements. Here, we will learn to perform OR and AND operations between every element of the array. Use the for Loop We can use the for loop to iterate through the array elements a nd do an OR operation of the array element with the resultant elements. Syntax Users can follow the syntax below to use the for loop to take OR or AND operation of every element. for () { ... Read More

The regex literals are regular expressions, a sequence of characters to match the strings. Sometimes, developers require to combine regular expressions. However, a regular expression is also one type of string, but we can’t concat them like a string using the ‘+’ operator. So, we first require to get flags from both regular expressions. After that, we must filter all unique flags and create a new Regex after combining multiple Regex literals. Syntax Users can follow the syntax below to concatenate regex literals in JavaScript. let allFlags = regex1.flags + regex2.flags; let uniqueFlags = new Set(allFlags.split('')); allFlags = [...uniqueFlags].join(''); let ...

In HTML, a table contains columns and rows. The table cells don’t contain the space between two cells by default. If we add some space between table cells, it can improve the UI of the table. In CSS, the ‘border-spacing’ property adds the space between the table space. Also, we need to use the ‘border-collapse’ CSS property with the ‘separate’ value while using the ‘border-spacing’ CSS property. Syntax Users can follow the syntax below to use the ‘border-spacing’ CSS property to add spaces between the table cells. table { border-collapse: separate; border-spacing: 3rem; ... Read More
