node format variable in string
To format a variable in a string in Node.js, you can use string interpolation or concatenation. Here are the steps to do it:
- String Interpolation: In Node.js, you can use template literals to interpolate variables into a string. Template literals are enclosed in backticks (`) and allow you to embed expressions inside
${}placeholders. The expressions inside the placeholders are evaluated and the result is inserted into the string.
Example:
javascript
const name = 'John';
const age = 25;
const message = `My name is ${name} and I am ${age} years old.`;
console.log(message); // Output: My name is John and I am 25 years old.

- String Concatenation: Another way to format a variable in a string is by concatenating the variable with the string using the
+operator.
Example:
javascript
const name = 'John';
const age = 25;
const message = 'My name is ' + name + ' and I am ' + age + ' years old.';
console.log(message); // Output: My name is John and I am 25 years old.
