+// NOTE - FoR LOOP
+
+/*******************
+ What is loop ? Loop is control structure of programming, it allows us to perform iteration, iteration is just a way of repeating must certain stuffs over and over again until a certain condition is met.
+*******************/
+
+// NOTE - syntax
+
+// for ([initialExpressions]; [conditionExpression], [increment])
+
+// E.g - just loop between numbers from 0 - 10
+
+for (let i = 2; i <= 10; i += 5) {
+  console.log("number" + i);
+}
+
+// NOTE  BLOCK SCOPE
+/*
+------------------------------------------------
+loop are also considered as block, just like if/else statements, any variables we define using let && const wont be accessible outside the scole
+
+------------------------------------------------
+*/
+
+for (let i = 0; i < 100; i += 10) {
+  const msg = "Number" + i;
+  console.log(msg);
+}
+
+// if i try to log `msg` here,  its not accessible i would a reference error
+// console.log(msg);
+
+// note - the code below will check in the loop when it meet the condition in the if block and log/display what is in there
+
+for (let i = 0; i <= 10; i++) {
+  if (i === 7) {
+    console.log("7 is my favorite number");
+  }
+
+  console.log("Number " + i);
+}
+
+/*
+# NESTED LOOOPs - at some points, its possible to nest two or loop in each other 
+*/
+
+for (let i = 1; i <= 12; i++) {
+  // console.log("number" + i);
+
+  for (let j = 1; j <= 12; j++) {
+    console.log(`${i} * ${j} = ${i * j}`);
+  }
+
+  console.log("number" + i);
+}
+
+// NOTE - the looop above can be used to solve multiplication tables stuffs
