Strings are text values and you’ll use them a lot while programming. In fact, all the words in this post are stored as one very large string in this website’s database.<\/p>\n
Every string value must start and begin with either a single or double quotation mark. You must use the same type of quotation mark (single or double) at the beginning and at the end of the string.<\/p>\n
Examples of strings:<\/p>\n
This tutorial assumes that you have completed the previous tutorials in this series OR are familiar with the following concepts:<\/p>\n<\/div>\n
To concatenate two strings (i.e., to join them together), use the concatenation operator ( You can append a value to a string by using the\u00a0 You can achieve this using string concatenation.<\/p>\n You can also use the += operator to achieve the same result.<\/p>\n The statement\u00a0 Sometimes you may want Apps Script to treat certain characters in a special way. For example, what if a string has quotation marks in it?<\/p>\n Consider the following string:\u00a0 To fix this, we need Apps Script to treat the single quotation mark in the word “let’s” just like any other character that is a part of the string. An escape character makes this possible.<\/p>\n If you prefix the single quotation mark in “let’s” with a backslash (\\), it will not terminate the string and will instead be treated like a regular character that is a part of the string.<\/p>\n The backslash is called an escape character and it makes Apps Script treat certain characters that follow it in a special way. Specifically:<\/p>\n In this tutorial, you learned about Strings in Apps Script.<\/p>\n+<\/code>). Both the concatenation operator and the addition operator have the same symbol\u00a0+<\/code>\u00a0but Apps Script will figure out which operation to perform based on the values being operated on. If the values are numbers, Apps Script will add them but if they’re strings, they’ll be concatenated.<\/p>\nExamples:<\/h3>\n

\"abc\" + \"def\"<\/code>\u00a0\/\/ will result in “abcdef”<\/li>\nAppending a string to another string<\/h2>\n
+=<\/code>\u00a0operator. For example, let us say you want to append the string “World” to the string “Hello”. The resulting output will be “HelloWorld”.<\/p>\nvar str = \"Hello\";\r\nstr = str + \"World\";\r\nLogger.log(str);<\/pre>\n
var str = \"Hello\";\r\nstr += \"World\";\r\nLogger.log(str);<\/pre>\n
str += \"World\"<\/code>\u00a0is an abbreviated version of\u00a0str = str + \"World\"<\/code>.<\/p>\nThe Escape character<\/h2>\n
'Let's go to the park today'<\/code>. The single quotation mark in the word “let’s” will make Apps Script think that the string has ended but this mark is actually a part of the string.<\/p>\n'Let's go to the park today'<\/code><\/p>\n'Let\\'s go to the park today'<\/code><\/p>\n\n
