Arrays and Loops

Both the "for" loop and "forEach" loop serve different purposes and have their own strengths. The forEach approach is ideal in scenarios where you simply need to iterate over array items and perform an action without the need for complex control flow. You can't

Here is where we are at during the last lesson: let fruits = ["Apple", "Banana", "Orange"]; function printFruits(fruit){ console.log(fruit); } fruits.forEach(printFruits); In the above code, we created a custom function called printFruits, and then we are providing its name as an

Now that you understand "for" loops in a detailed way, what if I tell you there is an easy shortcut to loop through each item inside an array? When it comes to looping over an array with a "for" loop statement, you have to: 1. Set

document.querySelector("#unsafe-passwords"); Whenever you select an HTML element using Javascript, a query is performed to find that element and then select it. And this querying takes a certain amount of time. For example, if you are selecting an element once, it could take 10 milliseconds (probably faster

If you remember, we have previously worked on an exercise of outputting a list of unsafe passwords onto a web page: Here is the final Javascript code for that exercise: let unsafePasswords = [ "123456", "password", "admin", "qwerty123", "password123" ]; //Select the parent

The problem: If you notice the conditional statement of the loop in the above diagram, we have provided the length of an array manually. We did so: 1. By manually counting the array length using our own brain 2. And then by manually typing the array length 5 inside the
