How many times has a test failed because of a simple typo in a variable name or an unexpected API response? We've all been there. In this episode we get our hands dirty with the core building blocks of TypeScript ā the types that every QA automation engineer uses daily. We start by comparing a JavaScript bug that silently passes with the TypeScript version that catches it immediately in the editor. Here's what we cover: š Core Types ā string, number, boolean and type inference āļø Template Literals ā building dynamic URLs and assertion messages ā ļø The Special Trio ā void, any, and unknown š« The `any` Trap ā why it defeats the purpose of TypeScript š”ļø Type Narrowing ā defensive coding with `unknown` š§ Practical Example ā putting it all together in a QA context This is Episode 1 of the TypeScript for Automation QA series. Based on Article 01 from my blog. ā¶ļø Next Episode: Arrays and Objects #playwright #typescript #framework #qa #softwaredevelopment #softwaretesting #api #ui #testing #quality #qualityassurance #testautomation #engineering
