If you are looking to find a certain character or set of characters in a string you can use the
.indexOf method to return the position of the character in integer format. For example
var myName = "My Name is Nick Coughlin" myName.indexOf("N") //11
Will return 11 because that is the position in the string of the letter N which is what we were searching for. You can also search for a set of character such as is.
var myName = "My Name is Nick Coughlin" myName.indexOf("is") //8
You can also use this property to check whether a character or string of characters is inside of a string using this method. If the character or string is not inside of the string the return will be -1
var myName = "My Name is Nick Coughlin" myName.indexOf("Max") //-1
And therefore we can simply check to see if it is true that the
.indexOf is ===-1. If it is then the character you are searching for is not present.
This will return the length of the string. For example:
This will select the character at whatever index position you specify in the parentheses:
Will capitalize a string.
This can be combined with .charAt to select and capitalize a specific letter. For example:
This property will return the string starting from the index which is chosen. Essentially slicing off the characters at the front.
Replace a character, or set of characters in a string with another character.
