So today I’m working on anagrams in coding. I need to write a function that checks if two strings are anagrams. We will start by saying that an anagram is a literary device where the letters that make up a word, phrase, or name are rearranged to create new ones. Two strings are considered anagrams if they contain the exact same characters with the same frequency, but possibly in a different order.
So we need to convert both strings to lowercase (to handle case sensitivity) and sort their characters alphabetically. Then compare the strings. If the sorted versions of both strings are the same, they are anagrams.
This is what I have:
function areAnagrams(str1, str2) {
return str1.toLowerCase().split('').sort().join('') === str2.toLowerCase().split('').sort().join('');
}
That one was pretty easy. Next function is where we write a function that generates a random password of a given length containing letters (uppercase & lowercase), numbers, and symbols. This one is a bit harder. The skeleton code is:
function generatePassword(length) {
// code here
}
I just know that I need to use Math.random() along with the character sets to generate a random password. Hmmm..
function generatePassword(length) {
const uppercase = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
const lowercase = "abcdefghijklmnopqrstuvwxyz";
const numbers = "0123456789";
const symbols = "!@#$%^&*()_+[]{}<>?,.";
const allCharacters = uppercase + lowercase + numbers + symbols;
let password = "";
}
Now I need to determine which loop to use for generating the password.
On another note, I’m feeling quite hungry at the moment. It’s lunchtime, and I think I should take a break to get something to eat. I’m not quite sure what I want, so I’ll head to the kitchen now; I can’t seem to think straight.
Tommy bought some spicy ramen from Costco, so I’m having that for lunch. I asked Lexi and Krissy how spicy it is, and Lexi suggested I should only use a drop of the red sauce. Haha! I took her advice, and just a drop was indeed quite spicy. Nevertheless, the ramen was good. I believe I’ve reached my entire sodium intake for today—or perhaps even for the week!
This past weekend was enjoyable. On Friday, both Kel and Tommy had dentist appointments, so I went along with them and waited in the lobby. I should probably make a dentist appointment for myself too. I also need to ask the dentist for a prescription for antibiotics, as I require them before any dental procedure due to heart surgery I had when I was younger. The dentist insists on this even for a routine cleaning. Karissa also needs to take antibiotics before any dental work.
After their appointments, we went over to Costco and picked up a few items. We now have electric toothbrushes! I’ve never used one before, so it’s taking a bit of getting used to. We also got a water flosser, which looks somewhat intimidating. I might give it a try tonight. Alexis came home on Friday night after having a fun time at her presentation.
On Saturday, Tommy and I went to the store where we picked up a few items before heading home. While I watched some videos on YouTube, he played a virtual reality game. Afterward, I spent some time watching him play Final Fantasy 7.
On Sunday, we took it easy for a while, during which Tommy practiced his saxophone. Later, we headed into the city, making a few stops to browse around. I’m currently on the lookout for a backpack, so we checked out several stores for that. Afterward, we enjoyed dinner at a Mexican restaurant. Once we finished eating, we went to the ice rink to watch Tommy’s hockey game. He scored a goal! We ended up getting home quite late.
Meanwhile, Lexi is in the process of cleaning her room. She’s shown me some old artifacts, including an ancient iPod, a mini iPad, and a Nintendo 3DS. She is keeping her 3DS and the rest of her old electronics will be given to Best Buy’s recycling program. She even gave me a mini USB cable to try out, but unfortunately, it doesn’t work. Lol.
Now, back to coding—I need to determine which loop to use for the function. I’m considering a for loop to iterate through the code effectively.
function generatePassword(length) {
const uppercase = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
const lowercase = "abcdefghijklmnopqrstuvwxyz";
const numbers = "0123456789";
const symbols = "!@#$%^&*()_+[]{}<>?,.";
const allCharacters = uppercase + lowercase + numbers + symbols;
let password = "";
for (let i = 0; i < length; i++) {
const randomIndex = Math.floor(Math.random() * allCharacters.length);
password += allCharacters[randomIndex];
}
return password;
}
}
- The function takes length as an argument to determine password length.
- Then it defines four strings containing different character types.
- After, we concatenate these strings into allCharacters, making it easy to select from all types.
- A loop runs length times, each time selecting a random character.
- The final password is returned.
For our next task, we will implement a Debounce Function. Debouncing is a technique that ensures a function is executed only after a specified delay when it is not invoked again within that timeframe. When a debounced function is called, it postpones execution until a period of inactivity has elapsed. If the function is invoked again during this delay, the timer resets. This mechanism helps to prevent unnecessary executions and enhances performance.
It does sound a bit confusing, so I plan to explore this topic further. The skeleton code for the debounce function is as follows:
function debounce(func, delay) {
let timer;
return function(...args) {
// code here
};
}
I believe I need to do some additional reading on this topic. By the way, Lexi has returned my canvas messenger bag, which I had completely forgotten about after six or seven years. I tend to hold onto my bags, and I have quite a collection. I wonder if it’s wise to keep all of them, although they are still in good condition. While I don’t collect shoes, I certainly do collect bags.
Lexi has mostly gotten rid of old papers and non-functional cables. She handed me her old state ID cards, and while I'm not sure what to do with them, I do like the picture. I find myself wanting a snack, but unfortunately, there aren't any in the house—perhaps that's for the best. Instead, I made myself a cup of hot tea to help curb my appetite. Tommy mentioned that my Kindle's battery is toast. It still works; it just needs frequent charging. We plan to look for a new one when they go on sale.
It’s such a lovely day today with temperatures in the 60s, although it is slightly windy. Merlin has spent most of the day outside, but Krissy just brought him in so he can take a nap. I didn’t want to mention that he was probably already sleeping outside.
