Log array element if string exists-CodePudding

I wanted to loop through an array and check if a string exists in the array elements and my code below partially works. The problem is currently it logs the array element if a specified string exists anywhere in the array element but what I want to do is log if the string is in the array element but also the same index position. To explain this better say one of my array elements is testing and the string I'm looking for is tes because tes is occurring in the index position 0,1,2 the element logs. But say my array element is not testing and the string I'm looking for is tes it won't log because even though the string exists it's in the wrong index. How can I achieve this? Thanks in advance.

const myArray = ['test blah', 'this is test', 'testing 234', 'nothing']

const check = 'te'
for (var i = 0; i < myArray.length; i  ) {
  if (myArray[i].includes(check)) {
    //should print myArray[0] and myarray[2]
    console.log(myArray[i]);
  }
}

You can use startsWith()

const myArray = ['test blah', 'this is test', 'testing 234', 'nothing']

const check = 'tes'
for (let i = 0; i < myArray.length; i  ) {
  if (myArray[i].startsWith(check)) {
    console.log(myArray[i]);
  }
}
