Question

Having tslint warnings (ES6) and still having some difficulty with its syntax.I am not sure how to convert to arrow functions.

var options = this.state.ProjectsArray.map(function (item, i) {
  var Trmp = item["ID"] + ";#" + item["Title"];
  return <option value={Trmp} key={item["ID"]}>{item["Title"]}</option> ;
});

Answer 1

Like this

var options = this.state.ProjectsArray.map((item, i) => {
  var Trmp = item["ID"] + ";#" + item["Title"];
  return <option value={Trmp} key={item["ID"]}>{item["Title"]}</option> ;
});

Remove function word and put => after the parameters
