Script Preparation code:

const asd1 = new Map().set(0b1000_0000, 1).set(0b0100_0000, 2).set(0b0010_0000, 3).set(0b0001_0000, 4).set(0b0000_1000, 5).set(0b0000_0100, 6).set(0b0000_0010, 7).set(0b0000_0001, 8);
const asd2 = { 0b1000_0000: 1, 0b0100_0000: 2, 0b0010_0000: 3, 0b0001_0000: 4, 0b0000_1000: 5, 0b0000_0100: 6, 0b0000_0010: 7, 0b0000_0001: 8 };
const asd3 = [ 0b1000_0000, 0b0100_0000, 0b0010_0000, 0b0001_0000, 0b0000_1000, 0b0000_0100, 0b0000_0010, 0b0000_0001 ];

Tests:

Map Check
const sizeSize = asd1.get(0b0000_0001) || 0;
Object Check
const sizeSize = asd2[0b0000_0001] || 0
Array Check
const sizeSize = asd3[asd3.indexOf(0b0000_0001)] ?? 0
Current Variant
const firstSizeByte = 0b0000_0001 let sizeSize = 0 if(firstSizeByte & 0b1000_0000) sizeSize = 1 else if(firstSizeByte & 0b0100_0000) sizeSize = 2 else if(firstSizeByte & 0b0010_0000) sizeSize = 3 else if(firstSizeByte & 0b0001_0000) sizeSize = 4 else if(firstSizeByte & 0b0000_1000) sizeSize = 5 else if(firstSizeByte & 0b0000_0100) sizeSize = 6 else if(firstSizeByte & 0b0000_0010) sizeSize = 7 else if(firstSizeByte & 0b0000_0001) sizeSize = 8
