What's the best way to loop through array of strings and replace values using RegExp? Array looks like this:

['./content1/App.js', './sample2/App.js', './exam/App.js']

I need to generate new array with values:

['content1', 'sample2', 'exam']

If the data item pattern is same in the question then you can try

const arr = ["./content1/App.js", "./sample2/App.js", "./exam/App.js"];
const result = arr.map((s) => s.match(/\.\/([^\/] )/)[1]);
console.log(result);

Using the map method of the Array prototype this can be achieved.

let newArray =['./content1/App.js', './sample2/App.js', './exam/App.js'].map((string)=>{
// code to replace string
//return the modified string
})
