Lecture 131:- ==vs==
In JavaScript, there are two operators for comparing values, which are == (loose or abstract equality) and === (strict equality).
The == operator compares the values on both sides and tries to convert them to the same type before comparing them. For example, 1 == '1' will return true because the string '1' will be converted to the number 1 before the comparison. This is known as type coercion and can lead to unexpected results.
On the other hand, the === operator compares the values on both sides without converting them. It checks if they are of the same type and have the same value. For example, 1 === '1' will return false because they are of different types.
It is generally recommended to use the === operator for comparisons in JavaScript to avoid any confusion and unexpected results due to type coercion.
