标题应该很容易解释。我如何打开以下数组:
[
"Bargain",
"deal",
"Consistent",
"Steady; regular",
"Accurately",
"a thing bought or offered for sale much more cheaply than is usual or expected.",
"Charge",
"demand (an amount) as a price for a service rendered or goods supplied."
]
进入下面的数组:
[
{"Bargain": "deal"},
{"Consistent": "Steady; regular"},
{"Accurately": "a thing bought or offered for sale much more cheaply than is usual or expected."},
{"Charge": "demand (an amount) as a price for a service rendered or goods supplied."}
]
解决方案可能很简单,但我想不出一种简单的方法来实现。我尝试制作2个单独的数组,并通过在第一个数组中取出奇数值并在第二个数组中取出偶数值(然后将它们合并之后)将它们过滤掉之后,对每个数组的元素进行过滤,但这似乎有些过分。
有没有简单的方法来实现它?
(是的,我知道'准确地'的定义是...很奇怪)

您可以通过简单的for
循环来实现:
const data = [
"Bargain",
"deal",
"Consistent",
"Steady; regular",
"Accurately",
"a thing bought or offered for sale much more cheaply than is usual or expected.",
"Charge",
"demand (an amount) as a price for a service rendered or goods supplied."
];
let result = [];
for (let i = 0; i < data.length; i += 2) {
result.push({
[data[i]]: data[i + 1]
});
}
console.log(result);

您可以像这样使用Array.from
:
int f = (int)difftime( time(NULL), start ) ;
int min = f / 60 ;
int sec = f % 60 ;
