Do I master Typescript if I master Javascript ? Is Typescript syntax different ? Answers appreciated, thank you !
minus-squareflurry@lemmy.worldlinkfedilinkEnglisharrow-up6·11 months agoTypeScript is a superset of JavaScript. It means any valid JavaScript is also valid TypeScript. You should start to learn basic JavaScript mechanisms : prototype inheritance, hoisting, scopes, this, event loop, type coercion. Once « JavaScript » sounds familiar you will embrace TypeScript which is JavaScript with steroids!
minus-squarenbafantest@lemmy.worldlinkfedilinkarrow-up1arrow-down5·11 months ago TypeScript is a superset of JavaScript. It means any valid JavaScript is also valid TypeScript. This is backwards. JS is superset and all TS compiles to valid JS. The vast majority of JS does not translate to Typescript as the JS is untyped.

minus-squareQuasari@programming.devlinkfedilinkEnglisharrow-up4·11 months agoTo be a superset, all elements of the subset must be contained within the superset. TypeScript is a superset of JavaScript as valid JS code(just with everything implicitly the any type) is valid TS code.
