js中判断多个值是否满足条件的写法

// 解决方案
// 1. 使用 && 运算符
if (a > 0 && b < 10 && c === 'hello') {
  // 条件全部满足时执行
  console.log('所有条件都满足');
}

// 2. 使用 Array.every() 方法
const values = [a, b, c];
const conditions = [
  (val) => val > 0,
  (val) => val < 10,
  (val) => val === 'hello',
];

if (values.every((value, index) => conditions[index](value))) {
  console.log('所有条件都满足');
}

// 3. 使用循环
let allTrue = true;
const checkValues = [a, b, c];
const checkConditions = [
    (val) => val > 0,
    (val) => val < 10,
    (val) => val === 'hello'
];

for(let i = 0; i < checkValues.length; i++){
    if(!checkConditions[i](checkValues[i])){
        allTrue = false;
        break;
    }
}

if(allTrue){
    console.log('所有条件都满足');
}


// 4. 使用reduce
const checkValuesReduce = [a, b, c];
const checkConditionsReduce = [
    (val) => val > 0,
    (val) => val < 10,
    (val) => val === 'hello'
];

const allConditionsMet = checkValuesReduce.reduce((acc, val, index) => acc && checkConditionsReduce[index](val), true);

if(allConditionsMet){
    console.log('所有条件都满足');
}

const values = [10, '20', { value: 30 }];
const conditions = [
  (val) => typeof val === 'number' && val > 5,
  (val) => typeof val === 'string' && parseInt(val) > 15,
  (val) => typeof val === 'object' && val.value > 25,
];

if (values.every((value, index) => conditions[index](value))) {
  console.log('所有条件都满足');
}

const isAGreaterThanZero = a > 0;
const isBLessThanTen = b < 10;
const isCEqualToHello = c === 'hello';

if (isAGreaterThanZero && isBLessThanTen && isCEqualToHello) {
  // ...
}
