TotalCount:100,PageSize:10,CurrentPage:1,TotalPages:10,HasNext:true,HasPrevious:falseIs there a way to transform the given string into key-value pairs?
TotalCount:100,PageSize:10,CurrentPage:1,TotalPages:10,HasNext:true,HasPrevious:falseLearn how to effectively utilize the String.split() method in JavaScript for splitting strings and then leveraging the reduce method to add key-value pairs into an object.
const data = "Name:John,D.O.B:01-01-1990,Location:New York,Hobbies:Tennis,Swimming";
const resultObject = data.split(',').reduce((accumulator, item) => {
const [key, value] = item.split(':');
return {...accumulator, [key]: value};
}, {});
console.log(resultObject);Here is a way to achieve the desired result:
let dataString = "Title:Ocean,Depth:100ft,Temperature:75°F,MarineLife:Various"
const dataObject = {};
dataString.split(",").forEach(item => {
dataObject[item.split(":")[0]] = item.split(":")[1]
});
console.log(dataObject);Implementing reduce function for type preservation
result = this.string.split(',').reduce((a: any, b: string) => {
const pairValue = b.split(':');
return {
...a,
[pairValue[0]]:
pairValue[1] == 'true'
? true
: pairValue[1] == 'false'
? false
: '' + (+pairValue[1]) == pairValue[1]
? +pairValue[1]
: pairValue[1],
};
}, {});
