I have the next code:
let dataList = [];
function filli(index, name, words){
dataList[index] = index;
dataList[index] = name;
dataList[index] = words;
}
filli(0, "David", "Testing this")
filli(1, "John", "My cellphone")
console.log(dataList)
I get in console the next:
$ node attempt.js
[ 'Testing this', 'My cellphone' ]
And my expected output in console would be:
[[0, "David", "Testing this"], [1, "John", "My cellphone"]]
But I don´t get that in console, as you can see I was trying to get that data in my filli function, sending an index, name, and words but it doesn't work.
I hope you can help me, thank you.
You are overriding existing values when you do dataList[index]= .... You need to add them as an array, something like this:
let dataList = [];
function filli(index, name, words){
dataList[index] = [index, name, words];
}
filli(0, "David", "Testing this")
filli(1, "John", "My cellphone")
console.log(dataList)
You are overriding the same value:
let dataList = [];
function filli(index, name, words){
dataList[index] = [] // first create new array
dataList[index][0] = index; // then assign to proper indexes
dataList[index][1] = name;
dataList[index][2] = words;
}
filli(0, "David", "Testing this")
filli(1, "John", "My cellphone")
console.log(dataList)
Ideally functions should return a value which your function doesn't at the moment. An alternative solution would be to add your arguments to an array and return that, and then push that result into the dataList array.
const dataList = [];
function filli(index, name, words){
return [index, name, words];
}
dataList.push(filli(0, 'David', 'Testing this'));
dataList.push(filli(1, 'John', 'My cellphone'));
console.log(dataList);
