Convert array of objects into an array but in a different format.

Question

I have an array of objects as shown below. I did a console.log(values); and got below result

["15- S&P", "us- ex US", "al- ex CL"]

0:"15- S&P"
1:"us- ex US"
2:"al- ex CL"
length:3
__proto__:Array(0)

I want the output in a array with values as follows.

[S&P, ex US, ex CL]

All values before the '-' are eliminated and values after '-' are taken and put in an array. for e.g. '15- S&P' is changed to 'S&P'. Can anyone please let me know how to achieve this.

["15- S&P", "us- ex US", "al- ex CL"].map(s => s.match(/- (.*)/).pop()) — E. Sundin

You could use Array#map and String#split to return just the text after - sign from every element.

var arr = ["15- S&P", "us- ex US", "al- ex CL"],
    res = arr.map(v => v.split("- ")[1]);
    
    console.log(res);

You may also try this;

var arr = ["15- S&P", "us- ex US", "al- ex CL"],
    res = arr.map(s => s.replace(/\w+-\s*([\w&\s]+)/,"$1"));
console.log(res);
