data structure to be implemented: const data = [{.}, {.},.];
// arrays
arrays = [[1,2,3],[4,5,6],[7,8,9],[10,11,12]];
// key keys
keys = ["a","b","c"];question: how to combine the above data into the following form?
data = [{a:1,b:2,c:3},{a:4,b:5,c:6},{a:7,b:8,c:9},{a:10,b:11,c:12}]; keys array must be written as follows: keys = ['a', 'baked,' c'] , otherwise, a
data = arrays.map(arr => {
let item = {}
arr.forEach((value, index) => {
item[keys[index]] = value
})
return item
})if such a structure can be guaranteed
arrays.map(item => {
let rt = {}
keys.forEach((key, idx) => {
rt[key] = item[idx]
})
return rt
})anyway, I already have the answer upstairs, so I, a rookie, will write an es5 to practice.
for (var i = 0; i < arrays.length; iPP) {
var obj = {};
for (var j = 0; j < keys.length; jPP) {
obj[j] = arrays[i][j];
}
data.push(obj);
} var data = arrays.map(item => {
const obj = {};
for(let i = 0; i < keys.length; iPP){
obj[keys[i]] = item[i];
}
return obj;

A solution that conforms to the meaning of the question function unique(arr) { const res = new Map(); return arr.filter((a) => !res.has(a) && res.set(a, 1)) } because map key is unique, you can change the an in res.has (a) to whate...
1. Use var: var a = []; for (var i = 0; i < 10; iPP) { a[i] = function () { console.log(i); }; } a[6](); 10 2. Use let var a = []; for (let i = 0; i < 10; iPP) { a[i] = function () { console.log(i); }; } a[6](); 6 quest...

The deconstruction of the function does not quite understand the red arrows in this. Why undefined? Is it not true that when let {XMagi y} = {XRO 0PersonyGl} , x can output equal to 0LI YQ 1, although XMagi y is a pattern and the assignment is assig...
