Day 6 Recap of 30DaysofJavaScript

August 10, 2022 • 2 min read

Finished Day 6! Let's recap!

So, what did I learn on Day 6 of 30DaysofJavaScript? Let's see!

Day 6 went over the various ways to use loops in JavaScript. We will go over each one briefly here.

Click here to follow along.

for Loops in JavaScript

For loops will continue to repeat it's block code until the condition specified is false.

                    
for (initialization, condition, increment/decrement) {
    // code goes here
}

The three conditions of the for loop are the initialization, condition, and increment/decrement. initialization creates a variable with an initial value. Conditions are typically a comparison to check if the variable has fufilled the condition. Then, you either increment or decrement the variable to get closer to the condition.

while Loops in JavaScript

WHile loops only have 1 condition, however, the variable changes in the loop rather than in the loop statement.

                    
let i = 0
while (i <= 5) {
    // code goes here
    i++
}

for of Loops in JavaScript

For of loops are used to iterate through elekments in an array without needing the index of each element.

                    
for (const element of arr) {
    // code goes here
}

break & continue

The break keyword can be used to interupt a loop, while continue can skip over interations of the loop.

                    
for (let i = 0; i <= 5 ; i++) {
    if(i == 2){
        continue
    }
    if (i == 4){
        break
    }
    console.log(i) // this will print 0 1 3
}

And this is the end of my recap of Day 6 of 30DaysofJavaScript. Loops are decently easy to understand.
