The JavaScript eval() is used to execute an argument. The code gets execute slower when the eval() method is used. It also has security implementations since it has a different scope of execution.ExampleHere’s how you can implement eval() function − var a = 30; var b = 12; var res1 = eval("a * b") + ""; var res2 = eval("5 + 10") + ""; document.write(res1); document.write(res2);
++a returns the value of an after it has been incremented. It is a pre-increment operator since ++ comes before the operand.a++ returns the value of a before incrementing. It is a post-increment operator since ++ comes after the operand.ExampleYou can try to run the following code to learn the difference between i++ and ++i − var a =10; var b =20; //pre-increment operator a = ++a; document.write("++a = "+a); //post-increment operator b = b++; document.write(" b++ = "+b);
