I have a Typescript project where I want to join all the values of an Object except one.
This is my Object:
let dataInit = {
"host": "CAPR",
"ua": "RMA",
"country": "VE",
"page":3
};
This is what I do:
let dataJoin = Object.values(dataInit).join(',')
This is what I get:
CAPR,RMA,VE,3
I need to know how to remove the 'page' property, this is what I want:
CAPR,RMA,VE
If you don't know the other attributes, you can first use Object.entries() to give you an array of arrays containing the keys and values. That array can then be filtered to remove the "page" element, mapped to just contain the value, and finally joined.
let dataInit = {
"host": "CAPR",
"ua": "RMA",
"country": "VE",
"page":3
};
console.log(
Object.entries(dataInit)
.filter(([key,val]) => key !== "page")
.map(([_,val]) => val)
.join(",")
)I would destructure the object first and create a new one
const { host, ua, country } = dataInit
const dataNew = { host, ua, country }
And then call the values join method on the new object.
You could filter the array resulted:
let dataJoin = Object.values(dataInit).filter(element => typeof element === "string").join(",");
Or you can use destructuring as presented in the other comments.
