+// 7. Strings
+
+// (i) Concatenation in Strings,
+const name = "Ayush"
+const repoCount = 19
+// Outdated Syntax,
+console.log(name + repoCount + " etc."); // Output : Ayush19 etc.
+// Modern day Syntax,
+console.log(`My name is ${name} and I have total ${repoCount} repositories on GiHub.`);
+// Output : My name is Ayush and I have total 19 repositories on GiHub.
+// Note: Benifits of this syntax is that we can use methods like, ${name.toUpperCase} e.t.c.
+
+// (ii) One more way of declaring strings,
+const gameName = new String('SuperMario') /* When we run this in Browser's console we can see
+some interesting things there.
+
+Some Methods of String, */
+// (a) Accessing 0th key of gameName,
+console.log(gameName[0]); // Output : S
+// (b) Accessing prototype,
+console.log(gameName.__proto__); // Output : {}
+
+// (c) Accessing methods of Prototype,
+console.log(gameName.length); // Output : 10
+console.log(gameName.toUpperCase()); // Output : SUPERMARIO 
+// This will not change our original string cause as we know about Stack.
+console.log(gameName.charAt(3)); // Output : e
+console.log(gameName.indexOf('M')); // Output : 5
+
+const discordName = "hitesh-hc"
+console.log(discordName.length); // Output : 9
+const newString = discordName.substring(0, 4) // It will not include the 4th one.
+console.log(newString); // Output : hite
+
+const anotherString = discordName.slice(-8, 4)
+console.log(anotherString); /* Output : ite
+Note : We cannot give negative values in substring but we can give negative value in slice. */
+
+const oneNewString = "    hitesh    "
+console.log(oneNewString.trim()) // Output : hitesh (will remove that spaces around the string.)
+
+const url = "https://ayush.com/ayush%20yadav"
+console.log(url.replace('%20', '-')); /* Output : https://ayush.com/ayush-yadav
+Also, */
+console.log(url.includes('ayush')) // Output : true
+
+console.log(discordName.split('-')); /* Output : [ 'hitesh', 'hc' ] (Converted into array with
+two strings) */
