How to convert array of string to array of object am using
for(var i in data){
arr.push(data[i]);
}
to get array of strings but need to convert array of strings to array of object.
Two ways:
var arrOfStrs = ["1","2","3","4"];
// first way - using the regular for
var arrObj1 = [];
for(var i = 0 ; i < arrOfStrs.length; i++)
{
arrObj1.push({item: arrOfStrs[i]});
}
console.log(arrObj1);
// second way - using for...in
var arrObj2 = [];
for(var key in arrOfStrs)
{
arrObj2.push({item: arrOfStrs[key]});
}
console.log(arrObj2);
Considering you have an array of strings like:
var arr = ["abc", "cde", "fgh"];
you can convert it to array of objects using the following logic:
var arrOfObjs = new Array(); //this array will hold the objects
var obj = {}; //declaring an empty object
for(var i=0; i<arr.length; i++){ //loop will run for 3 times
obj = {}; //renewing the object every time to avoid collision
obj.item = arr[i]; //setting the object property item's value
arrOfObjs.push(obj); //pushing the object in the array
}
alert(arrOfObjs[0].item); //abc
alert(arrOfObjs[1].item); //cde
alert(arrOfObjs[2].item); //fgh
var arrOfStrs = ["1", "2", "3", "4"];
var data = Object.entries(arrOfStrs).map(([key, value]) => ({
[key]: value
}))
console.log(data)
