I have this data :
let obj = {

]
],

Now, I want to loop through all the property of this object and make a new array of object. I mean property will be same but if the property value has array or array of array I want to make it a single array.
What I tried :
let additional = [];
for( property in obj ) {
if( Array.isArray( obj[ property ] ) ) {
additional.push({
[property] : obj[property]
});
} else if ( isValidUrl ( obj[ property ] ) ) {
additional.push({
[property] : '<a href="' obj[ property ] '">' obj[ property ] '</a>'
});
} else {
additional.push({
[property] : obj[property]
});
}
}
console.log(additional)
The output is :
[ { additional_image_link: [ [Array] ] },
{ aff_link:
'<a href="https://go.linkwi.se/z/11593-0/CD24352/?lnkurl=https://www.celestino.gr/el-GR/panteloni-me-pietes-lefko/prd/SK7732.1825/7?affiliate=linkwise&utm_source=linkwise&utm_medium=lw&utm_campaign=lw">https://go.linkwi.se/z/11593-0/CD24352/?lnkurl=https://www.celestino.gr/el-GR/panteloni-me-pietes-lefko/prd/SK7732.1825/7?affiliate=linkwise&utm_source=linkwise&utm_medium=lw&utm_campaign=lw</a>' },

But as you can see the additional_image_link has an array of array that's why the output is showing [Array]. But I want it's should be single array link all_sizes.
I have recursive function to loop through array of array :
function loop(data, outputArray) {
if(!Array.isArray(data)) {
outputArray.push(data);
} else {
data.forEach( ( element ) => {
if(Array.isArray(element)) {
loop(element, outputArray);
} else {
outputArray.push(element);
}
})
}
}
But no idea how to use it to the function.
May be I need to work on this block:
if( Array.isArray( obj[ property ] ) ) {
additional.push({
[property] : obj[property]
});
}
CodePudding user response：
You can use Array.isArray() to check if object property contains an array or not and then by using Array.flat() you can convert the multi dimensional array into single dimensional.

Object.keys(obj).forEach(key => {

obj[key] = obj[key].flat();
}
});
console.log(obj);CodePudding user response：
You can use Array.concat with spread operator to achieve this. However, this will work only 1 level. If you have a deeply nested object, You will have to create a recursive method.
[property] : [].concat(...obj[property])
