Function Debouncing and Throttling
Lodash provides _.debounce and _.throttle functions for controlling the rate of function execution. In JavaScript, you can implement debouncing and throttling using techniques like closures and timers setTimeout or setInterval.
Example: The example below shows the whichLodash feature that is Function Debouncing and Throttling that are available in plain JavaScript.
// Debouncing implementation in JavaScript
function debounce(func, delay) {
let timeoutId;
return function (...args) {
clearTimeout(timeoutId);
timeoutId = setTimeout(() => {
func.apply(this, args);
}, delay);
};
}
// Throttling implementation in JavaScript
function throttle(func, delay) {
let throttling = false;
return function (...args) {
if (!throttling) {
throttling = true;
func.apply(this, args);
setTimeout(() => {
throttling = false;
}, delay);
}
};
}
function search(query) {
console.log(`Searching for "${query}"...`);
}
const debouncedSearch = debounce(search, 300);
const throttledSearch = throttle(search, 300);
debouncedSearch("JavaScript");
throttledSearch("Debouncing");
throttledSearch("Throttling");
Output:
Searching for "Debouncing"...
Searching for "JavaScript"...
Lodash Features that are Available in JavaScript
Lodash is a JavaScript utility library that provides a wide range of functions. It offers an efficient API for working with arrays, objects, strings, functions, etc.
We’ll explore a few key features that are available in Lodash and demonstrate how they can be implemented using native JavaScript, reducing dependencies and improving code efficiency.
