Assignment operators

An assignment operator will assign the value of its right-side operand to its left-side operand and will return the newly assigned value. The left-side operand of an assignment operation must always be an assignable and valid identifier or property. Examples of this would include the following:

value = 1;
value.property = 1;
value['property'] = 1;

You can additionally use destructuring assignment, which enables you to declare your left-side operand as either an object-literal-like or array-like structure that designates the identifiers you wish to assign and the values you wish to be assigned:

[name, hobby] = ['Pikachu', 'Eating Ketchup'];
name;  // => "Pikachu"
hobby: // => "Eating Ketchup"
