Conditionals - if else 模式

本文探讨了多种优化条件判断的方法,包括使用正则表达式、对象字面量查询、逻辑运算符及折半搜索等,旨在提高代码效率和可读性。
//常规模式
if (type === 'foo' || type === 'bar') {}
// 正则
if (/^(foo|bar)$/.test(type)) {}
// 对象字面量查询
if (({foo:1, bar:1})[type]) {}
//逻辑运算符
(type === 'foo' || type === 'bar') && (type='1')
//折半搜索
if (value == 0) {
return result0;
} else if (value == 1) {
return result1;
} else if (value == 2) {
return result2;
else if (value == 3) {
return result3;
} else if (value == 4) {
return result4;
} else if (value == 5) {
return result5;
} else if (value == 6) {
return result6;
} else if (value == 7) {
return result7;
} else if (value == 8) {
return result8;
} else if (value == 9) {
return result9;
} else {
return result10;
}
==============转换为===============
if (value < 6) {
if (value < 3) {
if (value == 0) {
return result0;
} else if (value == 1) {
return result1;
} else {
return result2;
}
} else {
if (value == 3) {
return result3;
} else if (value == 4) {
return result4;
} else {
return result5;
}
}
} else {
if (value < 8) {
if (value == 6) {
return result6;
} else {
return result7;
}
} else {
if (value == 8) {
return result8;
} else if (value == 9) {
return result9;
} else {
return result10;
}
}
}
//一对一的数组和对象的查找结果
if (value == 0) {
return result0;
} else if (value == 1) {
return result1;
} else if (value == 2) {
return result2;
}
================转换为=================
// 定义一个包含所有结果的集数组
var results = [result0, result1, result2];
// 键值对应
return results[value];
