For the last part of the workshop, you will review how to find the index position of substring in a string. Remember that a substring is a part of a string.
Start by creating a variable called learningIsFunSentence and assign it the string value of "Learning is fun.".
You should have a variable called learningIsFunSentence.
assert.isNotNull(learningIsFunSentence);
Your learningIsFunSentence should hold the value of a string.
assert.isString(learningIsFunSentence);
You should assign the value of "Learning is fun." to the variable learningIsFunSentence.
assert.equal(learningIsFunSentence, "Learning is fun.");
console.log("Hi there!");
const botName = "teacherBot";
const greeting = `My name is ${botName}.`;
console.log(greeting);
const subject = "JavaScript";
const topic = "strings";
const sentence = `Today, you will learn about ${topic} in ${subject}.`;
console.log(sentence);
const strLengthIntro = `Here is an example of using the length property on the word ${subject}.`;
console.log(strLengthIntro);
console.log(subject.length);
console.log(`Here is an example of using the length property on the word ${topic}.`);
console.log(topic.length);
console.log(`Here is an example of accessing the first letter in the word ${subject}.`);
console.log(subject[0]);
console.log(`Here is an example of accessing the second letter in the word ${subject}.`);
console.log(subject[1]);
console.log(`Here is an example of accessing the last letter in the word ${subject}.`);
const lastCharacter = subject[subject.length - 1];
console.log(lastCharacter);
