The error message “property assignment expected” occurs when you are trying to assign a value to a variable or object property, but you forgot to include the assignment operator (=) between the variable/property and the value.
Here’s an example to better understand the issue:
var age; // Declaration of variable 'age'
age = 25; // Correctly assigning a value to 'age' using the assignment operator (=)
var person = { // Declaration of object 'person'
name: "John",
age: 30
};
person.name = "Jane"; // Correctly assigning a new value to the 'name' property of 'person' using the assignment operator (=)
In the first example, we declare a variable ‘age’ and then correctly assign it a value of 25 using the assignment operator (=). This will not cause the error.
In the second example, we declare an object ‘person’ and define properties ‘name’ and ‘age’ for it. Then, we correctly assign a new value “Jane” to the ‘name’ property of ‘person’ using the assignment operator (=). This will also not cause the error.
However, if you forget to include the assignment operator (=), you will encounter the “property assignment expected” error.
var age;
age 25; // Incorrect assignment without the equals sign (=)
In this incorrect example, we missed the equals sign (=) while assigning a value to the ‘age’ variable. This will trigger the “property assignment expected” error.
