I want to remove all the characters that appear after "$" sign in my string using javascript.
Is there any function in javascript which can help me achieve this. I am quite new to client side scripting.
Thanks.

slice() method to remove everything after a specific character, e.g. const removed = str. slice(0, str. indexOf('[')); . The slice method will return the part of the string before the specified character.
Using 'str. replace() , we can replace a specific character. If we want to remove that specific character, replace that character with an empty string. The str. replace() method will replace all occurrences of the specific character mentioned.
To remove the last character from a string in JavaScript, you should use the slice() method. It takes two arguments: the start index and the end index. slice() supports negative indexing, which means that slice(0, -1) is equivalent to slice(0, str. length - 1) .
How about this
astr.split("$")[0];
NB This will get you all of the characters up to the $. If you want that character too you will have to append it to this result.

You can try this regex, it will replace the first occurance of $ and everything after it with a $.
str.replace(/\$.*/, '$');
Input: I have $100
Output: I have $
