𝗧𝗵𝗲 𝗣𝗼𝘄𝗲𝗿 𝗼𝗳 𝗦𝘁𝗿𝗶𝗰𝘁 𝗠𝗼𝗱𝗲 𝗶𝗻 𝗧𝘆𝗽𝗲𝗦𝗰𝗿𝗶𝗽𝘁 You can enable strict mode in TypeScript with one line: "strict": true in your tsconfig.json. This turns on 8 safety checks at once.

Here are some key benefits:

• strictNullChecks stops null crashes
• noImplicitAny forces you to add proper types
• strictPropertyInitialization catches unset class properties
• useUnknownInCatchVariables makes error handling safer

To get even more safety, you can add noUncheckedIndexedAccess and noImplicitOverride.

On new projects, start with strict: true. On existing projects, enable each flag one at a time and fix errors before adding the next.
