How do I enable strict type checking in TypeScript?
To enable strict type checking in TypeScript, you need to set the strict
option to true
in your tsconfig.json
file.
What does enabling strict type checking do?
Enabling strict type checking helps catch errors at compile time, ensuring better type safety and reducing runtime errors.
Are there any specific flags I should consider?
Yes, besides strict
, you can enable individual flags like noImplicitAny
, strictNullChecks
, and strictFunctionTypes
for more control.
Can I enable strict type checking for just one file?
Strict type checking applies to the entire project, but you can use // @ts-check
in a JavaScript file to enable type checking for that file.
