Tests:

slice
const fromRight = false; const result = []; let index = fromRight ? input.length % size : 0; if (index !== 0) { result.push(input.slice(0, index)); } while (index < input.length) { result.push(input.slice(index, size + index)); index += size; }
slice right
const fromRight = true; const result = []; let index = fromRight ? input.length % size : 0; if (index !== 0) { result.push(input.slice(0, index)); } while (index < input.length) { result.push(input.slice(index, size + index)); index += size; }
splice
const fromRight = false; const source = [...input]; const result = []; if (fromRight) { result.push(source.splice(0, source.length % size)); } while (input.length > 0) { result.push(input.splice(0, size)); }
splice right
const fromRight = true; const source = [...input]; const result = []; if (fromRight) { result.push(source.splice(0, source.length % size)); } while (input.length > 0) { result.push(input.splice(0, size)); }
splice slice
const fromRight = false; const source = input.slice(); const result = []; if (fromRight) { result.push(source.splice(0, source.length % size)); } while (input.length > 0) { result.push(input.splice(0, size)); }
