Php
Numeric
Most of the time Javascript automatically converts to the right type.
/**
* Mathematical functions and expressions ...
* strings are automatically converted to numbers.
*
* The addition operator (+) doesn't convert strings to numbers.
*/
console.log("2" + "3"); // 23, not 5
console.log("6" / "3"); // 2
console.log(Number("2") + Number("3")); // 5
console.log(String(2) + String(3)); // 23 - Look Here
Boolean
In Javascript, a non-empty string is always true.
/**
* In Javascript "0" is not threated as false (like in PHP)
*/
let a = "0";
if (a) {
console.log("hello"); // hello
}
