Filling an array or slice with a repeated pattern

Looking for an efficient pure GO approach to copy repeating patterns into a slice, for a toy project, I ran a few tests and discovered a neat approach to significantly improve performance. For the toy project, I am using this to fill a background buffer with a specific RGB color pattern, so improving this performance significantly improved my acheivable framerate.

All the test were run with a buffer of 73437 bytes, allocated as follows

var bigSlice = make([]byte, 73437, 73437)

Fill the slice with the value 65 by looping through each element and setting the value

pattern:

^data:((?:\w+\/(?:(?!;).)+)?)((?:;[\w\W]*?[^;])*),(.+)$

// add some prototypes
String.prototype.limit = function(length = 150, tail = '...') {
    return this.substr(0, length) + (this.length > length ? tail : '');
};

// how to use:
'this is an string'.limit(5);

// or it can be like the below
let name = 'this is my name';
