Answer 1

const strings = ['teacher', 'friend', 'cricket', 'farmer', 'rose', 'talent', 'trainer'];
var stringOne='t'
var stringTwo='r'


var myVar = '['+strings.toString()+']';
console.log(myVar);
console.log(stringOne);
console.log(stringTwo);




    for (var i = 0; i < strings.length; ++i) {
        for (var j = 0; j < strings[i].length; ++j) {
          if(strings[i].startsWith(stringOne)&&strings[i].endsWith(stringTwo)); 
             console.log(strings[i]);
        }   
}


const stringsTwo = ['teacher', 'friend', 'cricket', 'farmer', 'rose', 'talent', 'trainer'];
var stringThree='p'
var stringFour='er'


var myVarTwo = '['+stringsTwo.toString()+']';
console.log(myVarTwo);
console.log(stringThree);
console.log(stringFour);
    for (var i = 0; i < stringsTwo.length; ++i) {
        for (var j = 0; j < stringsTwo[i].length; ++j) {
          if(strings[i].startsWith(stringThree)&&strings[i].endsWith(stringFour)); 
             console.log(stringsTwo[i]);
        }   
}
