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.
