^ != <<

In some languages, the '^' operator can be used for exponentiation, but in other popular development stacks, it operates as the exclusive OR (XOR) operator. Today, we'll discuss how this confusion can lead to errors, demonstrate their real-world examples in a popular library's queue implementation, and explain the consequences of these errors. Introduction The ^ operator is responsible for bitwise exclusive OR (XOR) in many modern programming languages, including Go. However, in other languages, such as Lua , VB.NET , Julia , R , and others, it represents exponentiation. Plus, people often use ^ to define the power of a number in everyday life, and it makes sense because the symbol kind of shows where the exponent should be. So, developers might use the exclusive OR ^ instead of the bitwise shift << to raise a number to the power of two. Although this error may seem far-fetched, we added a diagnostic rule to our Go analyzer inspired by a similar rule in CodeQL to detect instances of us
