How to trim suffix from the slice of bytes in Golang?
In Go language slice is more powerful, flexible, convenient than an array, and is a lightweight data structure. The slice is a variable-length sequence which stores elements of a similar type, you are not allowed to store different type of elements in the same slice.
In the Go slice of bytes, you are allowed to trim suffix from the given slice using TrimSuffix() function. This function returns a subslice of the original slice by slicing off the given trailing suffix string. If the given slice of bytes does not contain the specified suffix string, then this function returns the original slice without any change. It is defined under the bytes package so, you have to import bytes package in your program for accessing TrimSuffix function.
func TrimSuffix(ori_slice, sfx byte) byte
Here, ori_slice is the original slice of bytes and sfx represents the suffix. Let us discuss this concept with the help of the given examples:
Original Slice: Slice 1: !!GeeksforGeeks## Slice 2: Apple Slice 3: %geeks% New Slice: Slice 1: !!GeeksforGeeks# Slice 2: App Slice 3: %geeks%
