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

The output would be "ove".

Here's the step by step explanation:

1. 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.

2. In the given code, a.substring(3, 6); is used. Here, 3 is the start index and 6 is the end index.

3. 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'.

4. Therefore, the characters from index 3 to 5 (i.e., 'o', 'v', 'e') are extracted.

5. Hence, when console.log(result); is executed, "ove" is logged to the console.
