+// LOOPS AND ITERATION IN JS
+// For Loop
+
+// A loop is a control structure. It provides a way to do `iteration` in programming. 
+// Iteration is a process where you repeat something over and over again until a certain condition is or is met. 
+
+// There are many different kinds of loops in programming, 
+// and one of the most common loop is the `for` loop.
+
+// For Loop Syntax
+
+ for ([initialExpression]; [conditionExpression]; [incrementExpression])
+  // {statement}
+
+  /** 
+   The initial expression usually initializes a variable/counter
+   The condition expression is the condition that the loop will continue to run a long as it is met or until the condition is false
+   The increment/decrement expression is the expression that will be executed after each iteration of the loop
+   The statement is the code that will be executed each time the loop is run. To execute a `block` of code, use the `{}` syntax
+
+   */
+
+   // SIMPLE FOR LOOP FOR NUMBER 1 to 10
+for (let i = 1; i <= 10; i++) {
+  console.log("Number " + i);
+}
+
+// Output:
+// Number 1
+// Number 2
+// Number 3
+// Number 4
+// Number 5
+// Number 6
+// Number 7
+// Number 8
+// Number 9
+// Number 10
+
+// Can go upto 20,50,100 as much as you want.
+
+// Block scope
+
+// Loops are considered a `block`, just like if statements. 
+// Remember that variables using `let` and `const` are scoped to the block they are defined in. 
+// So if we define a variable in a loop, we can not access it outside of the loop.
+
+
+for (let i = 0; i <= 100; i += 5) {
+  const message = 'Number ' + i;
+  console.log(message);
+}
+
+console.log(message); // ReferenceError: message is not defined
+
+// However, if we use `var`, we can access the variable outside of the loop. This is not a good practice, but it is possible.
+
+for (let i = 0; i <= 100; i += 5) {
+  var message = 'Number ' + i;
+  console.log(message);
+}
+
+console.log(message); // Number 100
+
+// Testing Conditions
+
+for (let i = 0; i <= 10; i++) {
+  if (i === 7) {
+    console.log('7 is my favorite number');
+  }
+
+  console.log('Number ' + i);
+}
+
+// In the code above, we are testing the value of `i` to see if it is equal to 7. 
+// If it is, we will log the message "7 is my favorite number".
+
+// Nested For Loops
+
+for (let i = 1; i <= 10; i++) {
+  console.log('Number ' + i);
+  for (let j = 1; j <= 10; j++) {
+    console.log(i + ' * ' + j + ' = ' + i * j);
+  }
+}
+
+for(let k=0;k<=2;k++){
+    console.log('Number' + k);
+    for( let l=0;l<=10;l++){
+        console.log(k +' * ' + l + ' = ' + k*l)
+    }
+}
+
+// Looping Over Arrays
+
+Arrays have a `forEach()` method that allows you to loop over them. This is the most common way to loop over an array and we will be looking at `forEach()` and other array methods soon, however I do want to show you that we can loop over an array with a `for` loop.
+
+```JavaScript
+const names = ['Brad', 'Sam', 'Sara', 'John', 'Tim'];
+
+for (let i = 0; i < names.length; i++) {
+    console.log(names[i]);
+}
+
+```
+
+We simply specify the condition expression as long as `i` is less than the length of the array.
+
+If you wanted to find a specific iteration and index, you could do something like this
+
+```JavaScript
+for (let i = 0; i < names.length; i++) {
+  if (i === 2) {
+    console.log(names[i] + ' is the best');
+  } else {
+    console.log(names[i]);
+  }
+}
+
+```
+
+### Infinite Loops
+
+Infinite loops are something that you will probably run into at one point or another. They are loops that will never stop running. One common cause of this is forgetting to increment the counter. Then the condition is always met. This happens more with while loops, because of the way they are formatted.
+
+To purposely create an infinite `for` loop, we could do this:
+
+```JavaScript
+for (let i = 0; i < Infinity; i++) {
+  console.log('Number ' + i);
+}
+```
