Node.js console.info() Method
The console.info() method is an inbuilt application programming interface of the console module which is used to print messages to stdout in a newline. It is similar to the console.log() method.
Syntax:
console.info(data, args);
Parameters: This method has two parameters as mentioned above and described below:
- data: This parameter specifies the data to be printed.
- args: It is an optional parameter that specifies it to be passed as substitution values in messages passed to data. All passed args are sent to util.format().
Return Value: This method doesn't return anything but print the formatted message to stdout in a new line.
Example 1: The below examples illustrate the use of the console.info() method in Node.js:
Filename: app.js
// Node.js program to demonstrate the
// console.info() method
// Accessing console module
const console = require('console');
// Calling console.info() method
console.info("this is a sample info message!");
console.info("sample info message with args: %d", 39);
Run the app.js file using the following command:
node app.js
Output:
this is a sample info message! sample info message with args: 39
Example 2: The below examples illustrate the use of the console.info() method in Node.js:
Filename: app.js
// Node.js program to demonstrate the
// console.info() method
// Accessing console module
const console = require('console');
// Calling console.info() method
console.info("this is a %s" +
" sample info message!");
console.info("sample info message "
+ "with args: %d", 34);
console.info("info message: Warning "
+ "at function %s: line number"
+ " %d ff()", 96)
let isDebugMode = true;
console.custom_info = function (message) {
if (isDebugMode) {
console.log(message);
}
}
console.custom_info("custom info message");
Run the app.js file using the following command:
node app.js
Output:
this is a sample info message! sample info message with args: 34 info message: Warning at function ff(): line number 96 custom info message
Note: The above program will compile and run by using the node filename.js command.
