The Concept of Strings

Strings are commonly used to store and process text, using single quotes ('') or double quotes (""), either a pair of double quotes or a pair of single quotes.

Properties and Methods of Strings

length: represents the length of the string.

charAt: gets the character at the specified position

charCodeAt: obtains the ASCII code of the string

concat: concatenates strings

indexOf: finds the first occurrence of the string to search for; if not found, returns -1.

lastIndexOf has the same usage as indexOf, except that it searches from the end.
substr: this method extracts a specified number of characters from the string starting at the start index.

replace: replaces the content of the string, replacing only the found value.

split: converts the string into an array

toUpperCase() // convert to uppercase

toLowerCase() // convert to lowercase

Math usage:

Escape characters:

• \n: newline
• \t: tab
• \': single quote
• ": double quote
• \: backslash
• \r: carriage return
• \f: form feed
