Using console.log() Mocktest

The recommended approach for logging asynchronous operations using console.log() is to use separate console.log() statements for each asynchronous operation. Since asynchronous operations may have varying execution times and order, logging them separately ensures that each operation's output is captured and displayed correctly in the console. Including all asynchronous logs within a single console.log() statement may not provide clear visibility or accurate sequencing of asynchronous events, while disabling logging or using console.error() for all asynchronous logs is not suitable for general logging and monitoring of asynchronous operations. It is best to log asynchronous operations individually for better tracking and debugging of asynchronous code in JavaScript.

You can log formatted messages with variable values using console.log() by using special symbols like %s and %d in the message string. These symbols act as placeholders for variables or expressions, allowing you to insert dynamic content into log messages. For example, console.log("Name:", name, "Age:", age); will log "Name: John Age: 30" to the console with variable values substituted in the message. Using backticks or concatenation directly in the parentheses is not necessary for formatting log messages with variable values, as the special symbols in console.log() handle the formatting and substitution automatically.
