nodejs print variable in string

To print a variable in a string in Node.js, you can use string interpolation or concatenation. Here's an example of each method:

String Interpolation:

String interpolation allows you to embed variables directly into a string using template literals. To print a variable x in a string, you can use the ${x} syntax within backticks (` `) to define the string. Here's an example:

const x = 10;
console.log(`The value of x is ${x}`);

In this example, the variable x is printed within the string using ${x}.

String Concatenation:

String concatenation involves combining multiple strings and variables using the + operator. To print a variable x in a string, you can concatenate the variable with the surrounding string using the + operator. Here's an example:

const x = 10;
console.log('The value of x is ' + x);

In this example, the variable x is concatenated with the string 'The value of x is ' using the + operator.

Both methods will produce the same output: 'The value of x is 10'.

Please note that the examples provided are basic illustrations of how to print a variable in a string. In practice, you can use these techniques in more complex scenarios and with multiple variables.
