slice(begin, end) works on strings, as well as arrays. It returns a string representing the substring of the original string, from begin to end (end not included) where begin and end represent the index of characters in that string.
const string = "0123456789";
console.log(string.slice(0, 2)); // "01"
console.log(string.slice(0, 8)); // "01234567"
console.log(string.slice(3, 7)); // "3456"See also:

JavaScript – Keep Only First N Characters in a String | GeeksforGeeks
December 3, 2024 - While still widely supported, substr() is not recommended for new projects as it’s deprecated in JavaScript and may be removed in future versions. If you prefer to work with arrays, you can split the string into an array of characters and then use slice() on the array. This approach is a bit unconventional but works fine. ... Though not the most common, you can use string concatenation to get the first N characters by looping through the string or directly extracting the substring.

No jQuery needed! Just use the substring method:
var name = "cat1234"
var variable2 = name.substring(0, 3);

Use .slice(start, end) with start and end values:
var str = 'cat1234';
document.body.innerHTML = str.slice(0, 3);With javascript you can use a regular expression with .match() method to exclude the number and get the string value.
var str ='cat1234',
rg = /[a-zA-Z]+/g,
ns = str.match(rg);
document.body.innerHTML = ns[0];W3Resource
