How do I remove a property from a JavaScript object?

To remove a property from a JavaScript object, you can use the delete operator.
For example:

let obj = {

  foo: "bar",

  baz: 42

};



delete obj.foo;



console.log(obj); // { baz: 42 }

Keep in mind that the delete operator only removes the property from the object. It does not delete the value of the property.
For example:

let obj = {

  foo: "bar",

  baz: 42

};



let foo = obj.foo;

delete obj.foo;



console.log(foo); // "bar"

In this example, the delete operator removed the foo property from the obj object, but the value of the foo property ("bar") is still being stored in the foo variable.
