Chapter 04, Page 2 - Fixing the equals syntax in an if statement

The example of an if statement here explains how a single = sign is true. It should be if(hobby = "coding")

Incorrect code is:

if(hobby == "coding"){
  console.log("** I love coding too! **");
} else {
  console.log("** Can you teach me that? **");
}

Correct code is:

if(hobby = "coding"){
  console.log("** I love coding too! **");
} else {
  console.log("** Can you teach me that? **");
}

Chapter 14, Page 379 - Replaced Exercise 14.4 with correct solution

Solution for Exercise 14.4 is now fixed.

Chapter 05, Page 88 - While loops, corrected the console.log output

The output in the book currently shows 1-9. The correct output has to be from 0-9

Chapter 05, Page 89 - Added the missing console.log statement on line 8 to match the output

while (notFound && someArray.length > 0) {
  if (someArray[0] === "Louiza") {
    console.log("Found her!");
    notFound = false;
    console.log("false");
  } else {
    someArray.shift();
  }
}

Chapter05, Page 112 - Rephrased the 2nd paragrah on the page.

"We are looking for all the groups that have two or more names starting with an M. If we find such a group, we will log it."

Practice exercise 6.4, Page 129 - Fixed the incorrect referencing
