What is the primary function of the equality operator in programming?

The primary function of the equality operator in programming is to compare two values for equality. When you use this operator, it evaluates whether the values on either side are equal and returns a Boolean value: true if they are equal and false if they are not. This comparison is crucial in programming, especially in conditional statements and loops, where different execution paths depend on whether certain conditions are met.

Using the equality operator allows programs to make decisions based on the equality of variables or values, which is a foundational concept in logic and control flow in coding. Understanding this operator is essential for effective programming, as it enables developers to implement functionality that reacts to data comparisons dynamically.
