Convert Input Type Number in JavaScript

Day 18/100 JavaScript Type Conversion Implicit conversion = hidden behavior Explicit conversion = controlled logic Great developers don’t just write code They remove uncertainty from systems That’s what I practiced today Database ID Mismatch example #100DaysOfCode #Theodinproject #javascript #webDev

💡 Pure vs Impure Functions in JavaScript 🔹 Pure Function Same input → Same output. No side effects. const add = (a, b) => a + b; 🔸 Impure Function Depends on or changes external state. let total = 0; const addToTotal = (v) => total += v; 🚀 Why it matters? Predictable code. Easier testing. Fewer bugs. 👉 Write pure functions whenever possible. #JavaScript #CleanCode #FunctionalProgramming

JavaScript performance tip: Use const and let instead of var. Why? → Block scoping prevents bugs → const signals immutability → Better for JS engines to optimize Small syntax change. Big impact on code quality. #JavaScript #BestPractices #Performance

Day 5/100 of JavaScript Today’s Topic: Closures in JavaScript A closure is created when a function remembers variables from its outer scope even after that outer function has finished execution Example: function outer() { let count = 0; return function inner() { count++; return count; }; } const counter = outer(); counter(); // 1 counter(); // 2 Here, the "inner" function forms a closure over the "count" variable. Even though "outer()" has finished execution, "count" is preserved. Key understanding: Closures help in maintaining state and also enable data privacy by restricting direct access to variables #Day5 #JavaScript #100DaysOfCode

#Script Include and #GlideAjax >A script include in Service Now is a reusable javascript code which can be used whenever required in client script or server side script. >A script include is basically a group of multiple different functions. >To use the script include in the client side while creating the script include , we need to check the Glide Ajax enabled tick box. >Syntax for Glide Ajax var ga = new GlideAjax('script include name'); ga.addParam('sysparm_name','method name'); ga.addParam('sysparm_variable',variable value); ga.getXMLAnswer(callBack); function callBack(response){ alert(response); }

JavaScript array method I use daily: .find() vs .filter() find(): Returns first match (or undefined) filter(): Returns all matches (as array) One item needed? Use find() Multiple items? Use filter() Right tool, right job. #JavaScript #ArrayMethods #CodingTips

𝗟𝗼𝗼𝗽𝗶𝗻𝗴 𝗦𝘁𝗮𝘁𝗲𝗺𝗲𝗻𝘁𝘀 𝗜𝗻 𝗝𝗦 Looping statements in JavaScript repeat a block of code until a condition becomes false. You use loops to make your code shorter and easier to manage. JavaScript provides the following loops: - for Loop: used when you know how many times the loop should run - while Loop: runs as long as the given condition is true You can use loops to print numbers, find multiples, or count divisors. For example, you can print numbers from 1 to 5 using a for loop: for (let i = 1; i <= 5; i++) { console.log(i); } This prints: 1 2

Tech tip - making #javascript and #css slightly smaller I save space by setting a variable called '_' to 'this' at the start of a function that uses 'this' a lot. Saying 'background: aqua' is shorter than saying 'background-color: aqua'.

JavaScript - Debouncing for Search Input Problem: When typing in a search bar, multiple API requests are sent for each keystroke, leading to performance issues. Solution: Use a debounce function to limit the frequency of API requests, triggering the search only after the user has stopped typing for a specified amount of time.
