Is there a way in JavaScript to remove the end of a string?
I need to only keep the first 8 characters of a string and remove the rest.

To access the first n characters of a string in Java, we can use the built-in substring() method by passing 0, n as an arguments to it. 0 is the first character index (that is start position), n is the number of characters we need to get from a string. Note: The extraction starts at index 0 and ends before index 3.
You can use the substr function like this: echo substr($myStr, 0, 5); The second argument to substr is from what position what you want to start and third arguments is for how many characters you want to return.
To access the first n characters of a string in Python, we can use the subscript syntax [ ] by passing 0:n as an arguments to it. 0 is the starting position of an index. n is the number of characters we need to extract from the starting position (n is excluded).
slice() method to get the first N characters of a string, e.g. str. slice(0, 3) . The slice() method takes the start and stop indexes as parameters and returns a new string containing a slice of the original string.
const result = 'Hiya how are you'.substring(0,8); console.log(result); console.log(result.length);You are looking for JavaScript's String method substring
e.g.
'Hiya how are you'.substring(0,8); Which returns the string starting at the first character and finishing before the 9th character - i.e. 'Hiya how'.
