How can I join a the string of array inside an array?

How could I join a string inside an array of array? I’m trying to remove the space between inside array.

This is the array sample.

[
  [ 'time' ],
  [ 'user full name' ],
  [ 'affected user' ],
  [ 'event context' ],
  [ 'component' ],
  [ 'event name' ],
  [ 'description' ],
  [ 'origin' ],
  [ 'ip address' ]
]

I’m trying this to become like this.

[
  [ 'time' ],
  [ 'userfullname' ],
  [ 'affecteduser' ],
  [ 'eventcontext' ],
  [ 'component' ],
  [ 'eventname' ],
  [ 'description' ],
  [ 'origin' ],
  [ 'ipaddress' ]
]

This is my function i’m trying to run

const MakeArrayToSmall = (headerRow) => {
        let arrayToCheck = [];

        for (let i = 0; i < headerRow.length; i++) {
          let lowercaseLetter = headerRow[i].toLowerCase().split();
          arrayToCheck.push(lowercaseLetter)
        }
        return arrayToCheck
      
      };

      
      const samplearray = MakeArrayToSmall(headerRow)
      console.log(samplearray)

>Solution :

Loop the headerRow and then select the first element in the inner array and replace whitespaces with empty string headerRow[i][0].toLowerCase().replace(/\s/g, "")

const MakeArrayToSmall = (headerRow) => {
        let arrayToCheck = [];

        for (let i = 0; i < headerRow.length; i++) {
          let lowercaseLetter = headerRow[i][0].toLowerCase().replace(/\s/g, "");
          arrayToCheck.push(lowercaseLetter)
        }
        return arrayToCheck
      
      };
