Here's the object that I am working with, which contains arrays: https://i.sstatic.net/WPAF4.png
To extract its key values for further use, I'm trying to iterate over it using for in loop like this:
for (let key in gameObj){
console.log(key);
}
However, the loop doesn't seem to be entering at all to retrieve the arrays.
What could I possibly be missing?
Unfortunately, I don't have enough reputation to add this as a comment. For more information, please visit Is it possible to get the non-enumerable inherited property names of an object?
function findInheritedProperties(obj){
let allProps = []
, currentObj = obj
do{
let props = Object.getOwnPropertyNames(currentObj)
props.forEach(function(prop){
if (allProps.indexOf(prop) === -1)
allProps.push(prop)
})
}while(currentObj = Object.getPrototypeOf(currentObj))
return allProps
}
Everything is running smoothly. Feel free to take a look at the snippet.
let playerInfo = {
"name": ["Alice", "Bob", "Charlie", "David"],
"score": [100, 200, 300, 400]
}
for(let key in playerInfo){
console.log(key);
}To access the object in a for loop, simply use the key variable to reference each key value pair as if it were an array:
const gameObj = {
'99lEEbmV7s': ['37966', '37966', '37965', '37966', '0'],
'TggZdsbcje': ['37966', '37966', '37965', '37966', '0']
};
for (let key in gameObj){
console.log(gameObj[key]);
