Written by Rahul, Updated on September 28, 2018

This tutorial will help you to remove property of a JavaScript object using ‘delete’ operator.

Remove JavaScript Object Property

For this example, we have created an object with some default values.

var obj = {
    "webid": "101",
    "webname": "TecAdmin",
    "regex": "^https://.*"
};

var obj = {

"webid": "101",

"webname": "TecAdmin",

"regex": "^https://.*"

};

Now, use delete operator to delete the specific property from the JavaScript object.

delete obj.regex;

1	delete obj.regex;

Similarly, you can also use the following syntax to with delete operator.

delete obj['regex'];

1	delete obj['regex'];

Example:

Below is an working example of removing a property from java script object. Add below content in a HTML file and access in web browser. Now open console in browser to view the results.

var obj = {
    "webid": "101",
    "webname": "TecAdmin"
    "regex": "^https://.*"
};
console.log('-- Object data before remove --');
console.log(obj);

delete obj.regex;

console.log('-- Object data after remove --');
console.log(obj);

var obj = {

"webid": "101",

"webname": "TecAdmin"

"regex": "^https://.*"

};

console.log('-- Object data before remove --');

console.log(obj);

delete obj.regex;

console.log('-- Object data after remove --');

console.log(obj);
