consider this two arrays array y and array x i need to concatenates them but not after each other but be organised as in the form of array k the concatenate method just output them after each other
let x=['name','age','id'];
let y=['kyle',50,5050];
let k= x.concat(y);
the output i get is
k=['name','age','id','kyle',50,5050]
so how to merge them to get this output array
let k=['name':'kyle','age':50,'id':5050]
This is possible, but not as an array. You need an object.
const x = ['name', 'age', 'id'];
const y = ['kyle', 50, '5050'];
const k = {};
x.forEach((element, index) => {
k[element] = y[index];
});
console.log(k);
In fact, the javascript array doesn't look like this. We can have an array of objects or array of arrays
let keys=['name','age','id'];
let values=['kyle',50,5050];
var array = keys.map((el, i) => {
return {[keys[i]]:values[i]}
}); // as array of objects
var array = keys.map((el, i) => {
return [keys[i], values[i]];
}); // as array of arrays
of if you want a single object you can use
let obj = {};
keys.forEach((element, index) => {
obj[element] = values[index];
});
This should work for you
Note: k is not an array, it's an object read about JavaScript object here
let x = ['name', 'age', 'id'];
let y = ['kyle', 50, 5050];
let k = {};
x.forEach((item, index) => {
k[item] = y[index];
});
console.log(k);Simply with map:
let x = ['name', 'age', 'id'];
let y = ['kyle', 50, 5050];
k= x.map((prop, i) => [prop, y[i]]);
console.log(k);// [["name","kyle"],["age",50],["id",5050]]
