What is Comma Operator in JavaScript | JavaScript Tutorials in Hindi | Interview Question #35

In JavaScript, the comma operator is a binary operator that evaluates two expressions and returns the result of the second expression. It allows you to combine multiple expressions into a single expression, separating them with commas.

When the comma operator is used, the two expressions are evaluated from left to right. The value of the first expression is discarded, and the value of the second expression becomes the result of the entire expression.

However, it’s important to note that the comma operator is not commonly used in JavaScript, especially in everyday programming. It is primarily used in specific cases where a single expression is required, such as in for loops or when multiple expressions need to be evaluated in a certain order.
