I’m finally home after a busy morning out with Kel and Karissa. Karissa had an eye appointment, which went well, and she received new prescriptions. Afterwards, we headed to Costco to pick up her new glasses, which she will receive in a few weeks. We enjoyed lunch at Costco while waiting for Kel and her dad to join us. Now I’m back home for a bit, but I’ll need to head out again soon to pick up dinner ingredients. We’re having pastor tacos tonight.
On a different note, we’re working on writing a debounce function in our coding class. A debounce function is a higher-order function in JavaScript designed to limit the execution rate of another function. It ensures that the function is only executed after a specified delay has passed since the last time it was called. I’ve tried looking for examples online, but I’m still struggling to grasp the concept. I know the function will be structured as an arrow function, and the skeleton of the code looks like this:
function debounce(func, delay) {
let timer;
return function(...args) {
// Your code here
};
}
Another example involves an event listener attached to an input field that triggers a function with every keystroke made by the user. Without debouncing, this function executes on each individual key press, which can lead to performance issues, especially if it includes costly operations like API calls. Debouncing addresses this by ensuring that the function is executed only after the user has paused typing for a specified duration.
I’m beginning to grasp the concept, but I’m still uncertain about how to implement it in code.
I’ve been researching for a few hours and have come up with this so far:
const debounce = (func, delay) => {
let timer; // This will store the timer ID
return (...args) => {
clearTimeout(timer); // Clears any existing timer
}
}
I converted it into an arrow function, as I believe it will be more manageable. Tomorrow, when I have more time, I’ll delve into this further. For now, I’m waiting for Kel to pick me up so we can head to the store to get dinner supplies. Oh, it looks like she’s on her way. I should be going now.
