Javascript has functions which perform different operations on stings such as string comparison, searching a string in another string, converting from one case to another one. In javascript, the strings are used for storing and manipulating text. on this page, you will learn how to create strings, use them and make comparisons.

Learn the basics of javascript strings with code examples and small tutorials and descriptions on how each string function and method works. Strings are useful for holding data that can be represented in text form. some of the most used operations on strings are to check their length, to build and concatenate them using the and = string operators, checking for the existence or location of substrings with the indexof () method, or extracting substrings with the substring () method. Javascript defines many useful methods that operate on strings. before trying to use those methods individually, it is important to understand how those methods work at a more general level. because strings are objects, javascript uses the receiver syntax to call string methods. Let text = "we are the so called "vikings" from the north."; the string will be chopped to "we are the so called ". to solve this problem, you can use an backslash escape character. the backslash escape character (\) turns special characters into string characters:.
