Try Catch Block
Language: JavaScript
A try-catch block is used to mitigate errors in code and prevent program crashing during runtime. It 'tries' a block of code that could give an error. If the error is caught, it will execute a different block of code rather than crash the program (throw an error).
While Loop
Language: JavaScript
The while loop executes a block of code while a boolean expression evaluates to true. It terminates as soon as the expression evaluates to false. The boolean expression is evaluated before each iteration.

Language: JavaScript
