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 all the starting UTF-8-encoded code points from the given slice using TrimLeft() function. This function returns a subslice of the original slice by slicing off all the leading UTF-8-encoded code points which are specified in the given string. If the given slice of bytes does not contain the specified string in its left-hand side, 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 TrimLeft function.
func TrimLeft(ori_slicebyte, cut_string string) byte
Here, ori_slice is the original slice of bytes and cut_string represent a string which you want to trim in the given slice. 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: Apple^^ Slice 3: %geeks%
Final Slice: Slice 1: Welcome to GeeksforGeeks**** Slice 2: Learning how to trim a slice of bytes@@@@ Slice 3: ^^Geek&&
