336–372 No matter how good a programmer you are, you can’t control everything. When you write a risky method, you need code to handle the bad things that might happen. There is code that you can’t guarantee will work at runtime. …

312–334 There are no global methods in Java. However static methods are similar to global method in callability. Eg: Math.round() //rounds a floating point number to the nearest integer. Math.min() //takes two numerical primitives and returns the smaller Math.max() //takes two numerical primitives and returns the smaller Math.abs() //returns the…

JavaScript often abbreviated as JS, is a programming language that conforms to the ECMAScript specification. JavaScript is high-level, often just-in-time (JIT) compiled, and multi-paradigm. It has curly-bracket syntax, dynamic typing, prototype-based object-orientation, and first-class functions. The word “modern” when it comes to technologies is really subjective. For JS, 1995 modern…
