In JavaScript, a setter can be used to execute a function whenever a specified property is attempted to be changed. Setters are most often used in conjunction with getters to create a type of pseudo-property. It is not possible to simultaneously have a setter on a property that holds an actual value.
Examples
Defining a setter on new objects in object initializers
The following example define a pseudo-property current of object language. When current is assigned a value, it updates log with that value:
const language = {
set current(name) {
this.log.push(name);
},
log: [],
};
language.current = "EN";
console.log(language.log); // ['EN']
language.current = "FA";
console.log(language.log); // ['EN', 'FA']
Note that current is not defined, and any attempts to access it will result in undefined.
