-Machine code is very imperative. When we declare a variable the computer receives a lot of specific instructions on where to put it in which memory space, when to modify it and so on. Its very descriptive of how to do things. In contrast, as we go higher up the chain to a higher level language, it becomes more declarative. Instead of giving specific instructions of where to store it in memory etc, we just declare the variable with some sort of data and tell it what we need to get done but not how to do it. The computer takes care of that for us.

+
+`for` loops can be considered an imperative style of writing code
+
+```javascript
+for (let i = 0; i < 1000; i++) {
+    console.log(i) // -> 1,2,3,4...1000
+}
+```
+
+One way of making a `for` loop more declarative is to use `forEach()` instead
+
+```javascript
+[1,2,3].forEach(item => console.log(item)) // -> 1,2,3
+```
