script.js

const str1 = "Web Dev is amazing!"; 
    // => look for each of these separately:
    // - "development", 
console.log(str1.includes("development"));
    // - "Development", 
console.log(str1.includes("Development"));
    // - "web", 
console.log(str1.includes("web"));
    // - "ing", 
console.log(str1.includes("ing"));
    // - "Web"
console.log(str1.includes("Web"));


//concatenate two strings
const str2 = "Hey!"
const str3 = "How are you?"
let concatenate = str2 + str3
console.log (concatenate)

//Take out half of sentance:

let sentence = "This is one meaningless sentence which needs to be cut in half.";
let half = sentence.length / 2
console.log (sentence.slice (0, half))
// end result: This is one meaningless sentence

// ***hint: first calculate the length of 
// the sentence so you can calculate its half

//Capitalize:
//a) the whole name of the city where you are now
//b) the first letter of the city
//c) capitalize the middle letter if the city has an odd number of letters or two middle letters if the city has even number of letters (hint: you can use .charAt() and .slice())

let city = "Lisbon"
console.log (city.charAt(0))
console.log (city.slice(2,4))
