js对数组的一些处理?

var list = [
{time: '2022/08/18 14:37:15'},
{time: '2022/08/18 14:37:15'},
{time: '2022/08/18 14:37:15'},
{time: '2022/08/18 14:37:15'},
{time: '2022/08/18 14:37:15'}
]

以上数组处理得到:list = [
{time: '2022-08-18 14:37:15'},
{time: '2022-08-18 14:37:15'},
{time: '2022-08-18 14:37:15'},
{time: '2022-08-18 14:37:15'},
{time: '2022-08-18 14:37:15'}
]


回答:

日期中间的斜杠/改成中横线-吗?

list.map(item => {

return {

...item,

time: item.time.replace(/\//g, '-'),

}

})


回答:

const newList = list.map(x => {

return {

time: x.time.replace(/\//g, '-')

}

})


回答:

const data = JSON.parse(JSON.stringify(list).replace(/\//g,"-"));
