correct(delete scoped let):

			for (let e of s) {
				let A, B;
				if (use_positions) {
					let [a_, b_] = e.split(";");
					AA.set(a_.split(",")[0].split(' '));
					BB.set(b_.split(",")[0].split(' '));
					A = AA;
					B = BB;
				} else {
					const a = Math.floor(e / 67108864);
					const b = e - a * 67108864;
					const as = vertexOffset + a * 3;
					const bs = vertexOffset + b * 3;
					A = gpu_data.subarray(as, as + 3);
					B = gpu_data.subarray(bs, bs + 3);
				}
				lineRenderer.pushVertices(A, B);
			}
