Question
What would be logged to the console by the following block of code?let a = "ILoveProgramming"; let result = a.substring(3, 6);console.log(result);vePILogniing
Solution
The output would be "ove".
Here's the step by step explanation:
-
The
substring()method extracts the characters from a string, between two specified indices, and returns the new sub string. This method extracts the characters in a string between "start" and "end", not including "end" itself. -
In the given code,
a.substring(3, 6);is used. Here, 3 is the start index and 6 is the end index. -
The index of a string starts from 0. So, in the string "ILoveProgramming", the character at index 3 is 'o' and at index 6 is 'e'.
-
Therefore, the characters from index 3 to 5 (i.e., 'o', 'v', 'e') are extracted.
-
Hence, when
console.log(result);is executed, "ove" is logged to the console.
