How to use Type inference In Typescript
TypeScript’s type inference mechanism can automatically infer the types based on the provided arguments, reducing the need for explicit type annotations.
Example: TypeScript infers the types of result1, result2, and result3 based on the types of the arguments passed to the identity function. This reduces the need for explicit type annotations and improves code readability.
function identity<T>(arg: T): T {
return arg;
}
const result1 = identity("hello");
const result2 = identity(123);
const result3 = identity(true);
Output:
result1 is of type string
result2 is of type number
result3 is of type boolean
How to Create TypeScript Generic Function with Safe Type Matching ?
In TypeScript, generic functions offer a powerful tool for creating flexible and reusable code that can work with various data types. However, ensuring type safety is crucial to prevent runtime errors and maintain code reliability.
