JavaScript is great, but it's often better to use as little as possible in the front end.
Here are a few reasons why:
- JavaScript needs to be executed
- This costs CPU and memory
- 50% of daily internet users worldwide are mobile
- Not every mobile phone has the power to run a full SPA.
- Difference between == & === in JavaScript
Let's see how strict equality (triple equals) differs from loose equality (double equals) in JS
What would be the output of "2" ==you 2?
"2" == 2 will return true whereas the output of "2"===2 would be false.
This is because-
📌 == Converts both values into the same data type and returns true if both values are the same.
📌 === Only return true if both sides are the same data type and the same value, otherwise return false.
