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 Go strings, you are allowed to compare two strings with each other without any error even if they are written in different cases(lowercase and uppercase) with the help of EqualFold() function. Or in other, this function is used to check whether the specified strings are interpreted as UTF-8 strings and are equal under Unicode case-folding. This function returns true if the given strings are equal under Unicode case-folding or return false if the given strings are not equal under Unicode case-folding. It is defined under the strings package so, you have to import strings package in your program for accessing EqualFold function.
func EqualFold(str1, str2 string) bool
The return type of this function is of the bool type. Let us discuss this concept with the help of the examples:
Result 1: true Result 2: true Result 3: false Result 4: true Result 5: true Result 6: true
