To manipulate each item, we can utilize the `map` operator of Array. By applying Regex and the `replace` method of string, we can transform the 'Chosen' and 'password' fields.
const chosenRegex = new RegExp(/\{subjectsChosen:(.+)\}/, 'i')
const myText = "{subjectsChosen:Python,java,Angular}";
myText.replace(re, '$1'); // Python,java,Angular
Here is the complete code snippet that performs the transformation on each item:
const items = [
{
"subjectID": 1,
"Chosen" : "{subjectsChosen:Python,java,Angular}",
"password": "{studentpw:123456abcd}"
},
{
"subjectID": 2,
"Chosen" : "{subjectsChosen:SQL,Rprogram,React}",
"password": "{studentpw:987654zyxwv}"
}
];
const chosenRegex = new RegExp(/\{subjectsChosen:(.+)\}/, 'i')
const passwordRegex = new RegExp(/\{studentpw:(.+)\}/, 'i')
const transformedItems = items.map(item => {
return {
...item,
"Chosen": item.Chosen.replace(chosenRegex, '$1'),
"password": item.password.replace(passwordRegex, '$1')
}
});
console.log(transformedItems);
If we prefer to have a single regex for both fields, we could use the following approach:
const transformRegex = new RegExp(/\{(.+):(.+)\}/, 'i');
....
return {
...item,
"Chosen": item.Chosen.replace(transformRegex, '$2'), // Using $2 for the second group in the regex
"password": item.password.replace(transformRegex, '$2')
}
