What is the difference between normal strings and template literals when it comes to line breaks and extra white space?
Template literals, also known as template strings, are a feature introduced in ECMAScript 2015 (ES6) that offer a more flexible and expressive way to work with strings in JavaScript compared to normal strings. One of the key differences between template literals and normal strings is how they handle line breaks and extra white space. In
How can you include line breaks and extra white space within a string using template literals?
To include line breaks and extra white space within a string using template literals in JavaScript, you can utilize escape sequences and the newline character. Template literals, also known as template strings, provide a convenient way to create strings that contain dynamic content. They are enclosed within backticks (`) instead of single or double quotes.

What is the purpose of using backticks when creating template literals?
The purpose of using backticks when creating template literals in JavaScript is to provide a more flexible and concise way of working with strings. Template literals, also known as template strings, are a feature introduced in ECMAScript 6 (ES6) that allow for the embedding of expressions and multiline strings in a more readable and efficient

What are the three ways to create strings in JavaScript?
In the realm of web development, JavaScript is a powerful programming language that enables the creation of interactive and dynamic web pages. Strings, a fundamental data type in JavaScript, are sequences of characters enclosed within single quotes ('') or double quotes (""). They allow developers to work with textual data and manipulate it as needed.
How can you include a single quote character within a string that is enclosed in double quotes?
To include a single quote character within a string that is enclosed in double quotes in JavaScript, you can use either an escape character or a Unicode escape sequence. The escape character is represented by a backslash () and is used to escape special characters within a string. In this case, you would use the
Why is it important to use consistent quotes when working with strings in JavaScript?
Consistency in using quotes is essential when working with strings in JavaScript. It ensures that the code is readable, maintainable, and free from errors. In JavaScript, strings can be enclosed in either single quotes (''), double quotes ("") or backticks (“). While all three options are valid, it is important to choose one style and
What is the keyword used to declare a variable in JavaScript?
In the field of web development, specifically in JavaScript programming, the keyword used to declare a variable is "var". The "var" keyword is used to create a new variable and assign a value to it. It is an essential part of JavaScript syntax and plays a important role in storing and manipulating data within a

What happens if we try to change the value of a constant in JavaScript?
In the field of Web Development, particularly in JavaScript, constants are used to declare values that cannot be changed or reassigned once they are defined. When we try to change the value of a constant in JavaScript, an error is thrown, preventing the modification of the constant's value. This behavior is in accordance with the
How are constants different from variables in JavaScript?
In JavaScript, constants and variables are both fundamental concepts used for storing and manipulating data. However, they differ in their characteristics and behavior. Understanding the distinctions between constants and variables is important for effective programming in JavaScript. A constant is a value that cannot be changed after it has been assigned. It is declared using
What is the keyword used to declare a constant in JavaScript?
In JavaScript, the keyword used to declare a constant is "const". The "const" keyword is used to define a variable that cannot be reassigned after it has been initialized. It is commonly used to declare values that are intended to remain constant throughout the execution of a program. To declare a constant using the "const"
