javascript get all characters before a certain one

// say you wanted to collect all the chars before a slash (/).

myString = "12345.67890";

newString = myString.substring(0, myString.indexOf('/'));

console.log(newString);

// returns "12345"

Here is what the above code is Doing:
1. We create a string called myString and assign it the value “12345.67890”.
2. We create a new string called newString and assign it the value of myString.substring(0, myString.indexOf(‘/’)).
3. We log the value of newString to the console.

The substring() method takes two arguments: the starting index and the ending index.

In this case, we’re starting at index 0 and ending at the index of the first slash (/).

The indexOf() method returns the index of the first occurrence of a specified value in a string.

In this case, we’re looking for the first occurrence of a slash (/).

Since the slash is at index 5, the substring() method returns the characters from index 0 to index 5.
