Errors In Computer Programming There are three types of common errors in programming: Syntax Errors Runtime Errors Logical Errors i) Syntax Errors Syntax errors, also called parsing errors , occur at compile time in traditional programming languages and at interpret time in Google Apps Script. For example, the following line causes a syntax error because we used Variable name V caps. function errorTest(){ Var num1=100; } Try to Save ( Ctrl+S ) Error log:  Missing ; before statement. (line 47, file "RegEx") When a syntax error occurs in Google Apps Script, IDE don't allow to save the last changes. ii) Runtime Errors Runtime errors, also called exceptions , occur during execution (after compilation/interpretation). For example, the following line causes a runtime error because here the syntax is correct, but at runtime, it is trying to call a function that does not exist. function errorTest2(){ var test=method(); Logger.log(t

RegEx A regular expression, also called a regex , is a method for matching text with patterns. For example, a regular expression can describe the pattern of email addresses, URLs, telephone numbers, employee identification numbers, social security numbers, or credit card numbers. What Is a Regular Expression? A sequence of symbols and characters expressing a string or pattern to be searched for within a longer piece of text.

Regular expressions can be used to perform all types of text search and text replace operations.
