delete operator is used to remove an object property.
delete operator does not returns the new object, only returns a boolean: true or false.
In the other hand, after interpreter executes var updatedjsonobj = delete myjsonobj['otherIndustry']; , updatedjsonobj variable will store a boolean
value.
How to remove Json object specific key and its value ?
You just need to know the property name in order to delete it from the object’s properties.
delete myjsonobj['otherIndustry'];
let myjsonobj = {
"employeeid": "160915848",
"firstName": "tet",
"lastName": "test",
"email": "test@email.com",
"country": "Brasil",
"currentIndustry": "aaaaaaaaaaaaa",
"otherIndustry": "aaaaaaaaaaaaa",
"currentOrganization": "test",
"salary": "1234567"
}
delete myjsonobj['otherIndustry'];
console.log(myjsonobj);If you want to remove a key when you know the value you can use Object.keys function which returns an array of a given object’s own enumerable properties.
let value="test";
let myjsonobj = {
"employeeid": "160915848",
"firstName": "tet",
"lastName": "test",
"email": "test@email.com",
"country": "Brasil",
"currentIndustry": "aaaaaaaaaaaaa",
"otherIndustry": "aaaaaaaaaaaaa",
"currentOrganization": "test",
"salary": "1234567"
}
Object.keys(myjsonobj).forEach(function(key){
if (myjsonobj[key] === value) {
delete myjsonobj[key];
}
});
console.log(myjsonobj);
