Implicit return refers to a feature in some programming languages where the last expression evaluated in a function is automatically returned without explicitly using the ‘return’ keyword. This eliminates redundancy and makes code more concise.
For instance, consider this JavaScript arrow function:
const add = (a, b) => a + b;
Here, the result of a + b is implicitly returned. The function will evaluate the sum of a and b, and that value will be returned when the function is called.
