How do you get the length of a string in JQuery?

The task is to get the length of a string with the help of JQuery. We can find the length of the string by the jQuery .length property. The length property contains the number of elements in the jQuery object. Thus it can be used to get or find out the number of characters in a string.

Syntax:

$(selector).length
