JavaScript OR (||) variable assignment explanation - Stack ...
The boolean operators in JavaScript can return an operand, and not always a boolean result as in other languages. The Logical OR operator (||) returns the value of its second operand, if the first one is falsy, otherwise the value of the first operand is returned. For example: "foo" || "bar"; // returns "foo".
Logical OR assignment (||=) - JavaScript | MDN - MDN Web Docs
The logical OR assignment (||=) operator only evaluates the right operand and assigns to the left if the left operand is falsy. Logical OR assignment short-circuits, meaning that x ||= y is equivalent to x || (x = y), except that the expression x is only evaluated once.
javascript - Best Way for Conditional Variable Assignment ...
There are two methods I know of that you can declare a variable's value by conditions. Method 1: If the condition evaluates to true, the value on the left side of the column would be assigned to the variable.
JavaScript Logical OR assignment (||=) Operator - GeeksforGeeks
JavaScript Logical OR assignment (||=) Operator. This operator is represented by x ||= y and it is called a logical OR assignment operator. If the value of x is falsy then the value of y will be assigned to x. When we divide it into two parts it becomes x || ( x = y ).
JavaScript OR Assignment Operator - DEV Community
The JavaScript OR assignment operator can be used to quickly assign the value of a variable to one of two options based on one value and if it is null or undefined. The below code shows a function called 'getNotNull' which takes two parameters 'a' and 'b'.

The Bitwise OR Assignment Operator does a bitwise OR operation on two operands and assigns the result to the variable. Bitwise OR Assignment Example let x = 10;
JavaScript Comparison and Logical Operators - W3Schools
Comparison operators are used in logical statements to determine equality or difference between variables or values. Given that x = 5 , the table below explains the comparison operators: Operator
Theassignmentoperators are used to assign value based on the right operand to its left operand. The left operand must be a variable while the right operand may be a variable, number, boolean, string, expression, object, or combination of any other.
Variables are Containers for Storing Data. JavaScriptVariables can be declared in 4 ways: Automatically. Using var. Using let. Using const. In this first example, x, y, and z are undeclared variables. They are automatically declared when first used:
