In Go language, strings are different from other languages like Java, C++, Python, etc. It is a sequence of variable-width characters where each and every character is represented by one or more bytes using UTF-8 Encoding.
In Golang strings, you can check whether the string begins with the specified prefix or not with the help of HasPrefix() function. This function returns true if the given string starts with the specified prefix and return false if the given string does not start with the specified prefix. It is defined under the strings package so, you have to import strings package in your program for accessing HasPrefix function.
func HasPrefix(str, pre string) bool
Here, str is the original string and pre is a string which represents the prefix. The return type of this function is of the bool type. Let us discuss this concept with the help of an example:
Result 1: true Result 2: false Result 3: true Result 4: false Result 5: false Result 6: true
