JavaScript | String endsWith()

str.endsWith() function is used to check whether the given string ends with the characters of the specified string or not.

Syntax:
str.endsWith(searchString, length)

Arguments
The first argument to this function is a string of characters searchString which is to be searched at the end of the given string. The second argument to the function is length which determines the length of the given string from the beginning to be searched for the searchString.

Return value
This function returns the Boolean value true if the searchString is found else it returns the Boolean value false

Examples for the above function are provided below:

Example 1:



var str = 'It is a great day.'
print(str.endsWith('day.'));

Output:

true

In this example the function endsWith() checks for searchString at the end of the given string. Since the searchString is found at the end, therefore this function returns true.

Example 2:

var str = 'It is a great day.'
print(str.endsWith('great'));

Output:

false

In this example the function endsWith() checks for searchString at the end of the given string. Since the searchString is not found at the end, therefore this function returns false.

Example 3:

var str = 'It is a great day.'
print(str.endsWith('great',13));

Output:

true

In this example the function endsWith() checks for searchString at the end of the given string. Since the second argument defines the end of the string at index 13 and at this index searchString is found to end, therefore this function returns true.
