Removing Unnecessary Characters from a String with JavaScript

Removing Unnecessary Characters from a String with JavaScript

I am currently fetching NBA game data from an API using Javascript, and I am facing a challenge in manipulating it. Each game entry is stored as its own object, with information presented in the following format:

Date: "Nov 7, 2014"
Opponent: "@ Charlotte"
Result: "L"
Score: "122-119"
Spread: "+1.5"

Depending on whether the team is playing home or away, there is either a "@" or a "vs" preceding the opponent's name for that specific game. My goal is to remove this prefix so that the "Opponent" key only contains the name of the opponent without any unnecessary characters.

I attempted to achieve this by using

gameLog[i].Opponent = (gameLog[i].Opponent.split(" ").pop

to eliminate any characters before the space, but unfortunately, this approach messes up the data when dealing with team names containing spaces like "New York" or "Los Angeles".

Answer №1

This function extracts a substring from the original string, beginning at the first occurrence of a white space character. For example:

@ California = a new substring starting after the @ symbol. -> California

gameLog[i].Location = gameLog[i].Opponent.substr(gameLog[i].Opponent.indexOf(' ')+1);

Perhaps something like this could provide a solution.

var location = "@ Nashville";
var rival = "vs Chicago";

function determineLocation(place){

    // Checking if it is an away game
    if ( place.indexOf("@") === 0 ){

        return place.replace("@","").trim();

    } else {

        return place.replace("vs","").trim();
        
    }

}

console.log( determineLocation(location) );
console.log( determineLocation(rival) );

Utilizing regular expressions is a handy technique for eliminating unwanted characters when iterating through an array of objects.

for (let index = 0; index < dataArr.length; index++) {
      dataArr[index].Opponent = dataArr[index].Opponent.replace(/@\s|vs\s/g, '');
}

To extract a part of a string in JavaScript, you can utilize the substr() method:

var text = "@ San Francisco";
var result = text.substr(2);

The extracted substring will be: San Francisco

In case there is a space after the "@" symbol, and you need to include it in the extracted string, you can use this alternative approach:

var text = "@ San Francisco";
var result = text.substr(text.indexOf(' ')+1);
