How To Join Array Of Strings In Javascript

I want to join an array of result = ['July',' ','1st'] into result = ['July 1st']. I also want to have the comma removed. I have tried result.join() and result.join(',') but it di

Solution 1:

You just need to join it and put into an array...:

result = [result.join('')];

Solution 2:

You need to specify empty string in .join function

var result = ["July"," ","1st"]
result.join('') // "July 1st"

EDIT: and if you need output in array then it will

[result.join('')] // ["July 1st"]

Solution 3:

var b ="";

result.forEach(function(a){b = b.concat(a);});

console.log(b);

Solution 4:

You can also use the javascript reduce() function as follows:

var result = [result.reduce(function(previousString, currentString) {
                return previousString + currentString 
             })];
