Why TypeScript is better than JavaScript for production

⚡ JavaScript & TypeScript Daily Refresher #62 👉 When do you use export default and when export in TypeScript? 💡 Use export for named exports when a file contains multiple items. Use export default for a single main value — like React components or utility modules with one primary function. ✨ I post daily JS/TS refreshers — follow for the next one! #JavaScript #TypeScript #React #WebDevelopment

TypeScript Tip 💡 Ever wondered when to use interface vs type? Here’s the quick rule: 👉 Use interface when you’re defining the shape of an object (and might extend it later). 👉 Use type when you need unions, intersections, or complex types. Both are powerful but interface is better for structure, type for flexibility. #TypeScript #WebDevelopment #JavaScript #CodingTips

⚡ JavaScript & TypeScript Daily Refresher #85 👉 What is a predicate in TypeScript? 💡 A predicate is a special return type used in custom type guards — it tells TypeScript that a function checks a specific type. Example: function isString(value: unknown): value is string { return typeof value === "string"; } ✨ I post daily JS/TS refreshers — follow for the next one! #JavaScript #TypeScript #TypeGuards #WebDevelopment

⚡ JavaScript & TypeScript Daily Refresher #84 👉 What are type guards in TypeScript? 💡 Type guards are runtime checks that let TypeScript know more about a variable’s type within a block — for example: if (typeof value === "string") { /* value is a string here */ } ✨ I post daily JS/TS refreshers — follow for the next one! #JavaScript #TypeScript #TypeGuards #WebDevelopment

Read an interesting article today about the debate: Vanilla JS vs Frameworks for smaller projects. Where do you draw the line As a beginner, I find Vanilla JS helps me understand the core concepts better Agree Disagree #JavaScript #FrontendDebate #WebDevelopment"

⚡ JavaScript & TypeScript Daily Refresher #70 👉 How do you convert a string to a number in JavaScript/TypeScript? 💡 There are many ways — Number(), parseInt(), parseFloat() — but I personally prefer the unary plus (+) operator: +value is short and clean! ✨ I post daily JS/TS refreshers — follow for the next one! #JavaScript #TypeScript #CodingTips #WebDevelopment

⚡ JavaScript & TypeScript Daily Refresher #89 👉 What are function overloads in TypeScript? 💡 Function overloads let you define multiple call signatures for one function, so TypeScript can offer better type safety and autocomplete based on how the function is called. ✨ I post daily JS/TS refreshers — follow for the next one! #JavaScript #TypeScript #FunctionOverloads #WebDevelopment

Hoisting is JavaScript’s way of moving declarations (not initializations) to the top of their scope before execution. 🧩💡 Tip: Always declare before use — hoisting can surprise you! #JavaScript #WebDev #FrontendTips #StructuredClone #JSDeepCopy #CodingTips #WebDevelopment Examples:

⚡ JavaScript & TypeScript Daily Refresher #64 👉 What happens to default parameter values after TypeScript compiles to JavaScript? 💡 TypeScript converts them into plain JS checks. It adds an if statement to see if the argument is undefined, and if so, assigns the default value — ensuring consistent behavior at runtime. ✨ I post daily JS/TS refreshers — follow for the next one! #JavaScript #TypeScript #Compilation #WebDevelopment

⚡ JavaScript & TypeScript Daily Refresher #73 👉 I have a User type where all properties are required, but for a patch operation, I want to make all properties optional except id. How would you do this? 💡 Use utility types — Partial<User> makes all properties optional, and you can combine it with Pick or & to keep id required: type PatchUser = Partial<User> & Pick<User, "id"> ✨ I post daily JS/TS refreshers — follow for the next one! #JavaScript #TypeScript #UtilityTypes #WebDevelopment
