How do I use either a template literal or string concatenation to log this message?

by

Summary

The task requires using either a template literal or string concatenation to log a message to the console. The message includes the result of checking if a sentence contains the word “freeCodeCamp”. Template literals and string concatenation are two methods that can be used to achieve this.

Root Cause

The root cause of the problem is the need to dynamically include the result of the includes() method in a logged message. The includes() method returns a boolean value indicating whether the string contains the specified word.

Why This Happens in Real Systems

This issue arises in real systems when:

  • Logging dynamic information is necessary
  • User input or variables need to be included in messages
  • The inclusion of specific words or phrases in text needs to be checked and reported
    Some key points to consider are:
  • Dynamic logging: The ability to log messages that include variable information
  • String manipulation: The need to concatenate or template strings to include dynamic data
  • Conditional checks: The use of methods like includes() to check for specific conditions

Real-World Impact

The impact of not using template literals or string concatenation correctly can lead to:

  • Inaccurate logging
  • Difficulty in debugging
  • Inability to dynamically report information
  • Readability issues: Messages that are hard to understand due to poor string construction

Example or Code

const fccSentence = "freeCodeCamp is a great place to learn web development.";
console.log("Here are some examples of the includes() method:");
const hasFreeCodeCamp = fccSentence.includes("freeCodeCamp");
console.log(`fccSentence.includes("freeCodeCamp") returns ${hasFreeCodeCamp} because the word "freeCodeCamp" is ${hasFreeCodeCamp? "" : "not "}in the sentence.`);

How Senior Engineers Fix It

Senior engineers approach this problem by:

  • Identifying the need for dynamic logging
  • Choosing the appropriate method (template literal or string concatenation) based on readability and the complexity of the string
  • Ensuring that variables are correctly included in the logged message
  • Best practices: Following established guidelines for logging and string manipulation to ensure clarity and maintainability

Why Juniors Miss It

Juniors might miss this because:

  • Lack of experience with dynamic logging
  • Uncertainty about when to use template literals versus string concatenation
  • Oversight in including variables in logged messages
  • Training and practice: The need for juniors to practice and train in logging and string manipulation techniques to develop their skills.
