In JavaScript, you can remove a property from an object using the delete operator. Here's how you can do it:
var obj = { property1: "value1", property2: "value2", }; // Remove a property delete obj.property1; // Check if the property is removed console.log(obj.property1); // Output: undefined
In the above example, we have an object obj
with two properties
property1
and property2.
To remove
property1
, we use the delete
operator followed by the object name and the property name
(delete obj.property1)
.
After removing the property, if you try to access it, it will return undefined
, as demonstrated by
console.log(obj.property1)
.
Note that the delete
the operator removes the property from the object directly. If the property is inherited from a prototype chain, it will not affect the original prototype object.
