I was presented with the following string:
result:tie,player:paper,computer:paperOne way to handle this could be splitting it into arrays, creating an object, and parsing it. However, this approach may not be ideal.
Is there a better method to convert this string into an object?
let string = "result:tie,player:paper,computer:paper"
To handle this specific string, my approach would be to convert the string into valid JSON by enclosing the keys and values in double quotes, and then utilizing JSON.parse:
const string = "result:tie,player:paper,computer:paper";
const json = '{' + string.replace(/(\w+):(\w+)/g, `"$1":"$2"`) + '}';
console.log(JSON.parse(json));However, ideally, any source providing you with that string should present it in JSON format instead of requiring you to rely on a workaround like this for handling flawed input.
Break apart using ,, go through each item, and break down further by splitting at : to create object key/value pairs. Utilize destructuring for simplicity:
let text = "result:win,user:rock,computer:scissors";
let objects = {};
let propertiesArray = text.split(",");
propertiesArray.forEach(item => {
var [property, value] = item.split(":");
objects[property] = value;
});
console.log(objects);To extract key and value pairs from a string formatted as "key:value" separated by commas, first split the string on commas to get individual key-value tokens. Then further split each token on a colon to separate the key and value components. Add these key-value pairs to an object that aggregates all the pairs.
var data = "name:John,age:30,country:USA";
var parsedData = data.split(',').reduce((result, token) => {
var [key, value] = token.split(':');
result[key] = value;
return result;
}, {});
console.log(parsedData);What is the impact if JQuery attempts to access elements that do not exist? Will there be any significant CPU overhead other than script loading? Does it matter if this is done for a class or an id? For optimization purposes and to minimize simultaneous c ...
