Is there a way to remove the array elements cctype, cctypologycode, and amount if they are empty? What would be the most efficient approach?
{
"ccInput": [
{
"designSummaryId": 6,
"CCType": "A",
"CCTypologyCode": "A",
"Amount": "1"
},
{
"designSummaryId": 7,
"CCType": "",
"CCTypologyCode": "",
"Amount": ""
},
]
}
ccInput[1] needs to be removed from the array
To eliminate certain elements from an array, utilize the Array.prototype.filter() method.
If you prefer to maintain immutability, you can achieve this by making a copy of each object property using the spread operator and then filtering based on the ccInput property:
const obj = {ccInput:[{designSummaryId:6,CCType:"A",CCTypologyCode:"A",Amount:"1"},{designSummaryId:7,CCType:"",CCTypologyCode:"",Amount:""}]};
const result = { ...obj, ccInput: obj.ccInput.filter(x => x.CCType && x.CCTypologyCode) };
console.log(result);Alternatively, if you want to directly modify the object, simply update the ccInput property:
const obj = {ccInput:[{designSummaryId:6,CCType:"A",CCTypologyCode:"A",Amount:"1"},{designSummaryId:7,CCType:"",CCTypologyCode:"",Amount:""}]};
obj.ccInput = obj.ccInput.filter(x => x.CCType && x.CCTypologyCode);
console.log(obj);When it comes to TypeScript, my knowledge is limited, but I am aware that you have the option to initialize an array with []. If you are trying to remove only a specific section of an array without clearing the entire thing, one straightforward method I recommend is to set each element to a neutral value - such as 0 for numbers, '' for characters, "" for Strings, and so on.
