How do inline functions work in different programming languages?

How do inline functions work in different programming languages?

Inline functions are functions that are expanded in line when they are called, rather than being invoked through a traditional function call. This can improve performance by reducing the overhead of function calls.

Can you give me examples of inline functions in C++ and JavaScript?

Sure! In C++, you can define an inline function like this:

inline int add(int a, int b) {
    return a + b;
}

In JavaScript, you can use arrow functions as inline functions:

const add = (a, b) => a + b;

What are the advantages and disadvantages of using inline functions?

The advantages include faster execution due to reduced function call overhead and potential optimization by the compiler. However, disadvantages can include increased code size and potential for code bloat if used excessively.

Are there any languages where inline functions are not supported?

Most modern programming languages support some form of inline functions, but older languages or those with different paradigms may not have this feature. For example, older versions of Java did not support inline functions.
