arr = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9];
const _ = require('lodash');
let outArr = [];
try {
arr.forEach...);
} else {
throw new Error('brack');
}
});
} catch (err) {
}
方法二：污染forEach...obj < 3) {
outArr.push(obj);
} else {
return false;
}
});
方法三：用替代品
1：用lodash的_....forEach代替
const arr = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9];
const _ = require('lodash');
let outArr = [];..._.forEach(arr, (index, obj) => {
console.log(obj);
if (obj < 3) {
outArr.push(obj);
