Using TypeScript arrow functions to define parameters

When setting "noImplicitAny": true in TypeScript, you may encounter the following errors:

Parameter 'x' implicitly has an 'any' type

This error can occur with the code snippet:

.do(x => console.log(x));

Another error you might see is:

',' expected

when using:

.do(x: any => console.log(x));

Answer №1

Through my exploration, I discovered the proper method for defining a type for the parameter is by including parentheses:

.do((x: any) => console.log(x));
