Testing yourthisknowledge in JavaScript: What is the output of the following code? var length = 10; function fn() { console.log(this.length); } var obj = { length: 5, method: function(fn) { fn(); arguments[0](); } }; obj.method(fn, 1); ...
Code Explanation Here is the simple code explanation for the above code: The code extracts text enclosed in double quotes from a string. It begins with a string containing two quoted phrases. The split() method divides the string into an array called parts at each double quote. The filter(...
Another approach is to split the string into an array using thesplit()method, remove the unwanted element (in this case, the first element), and then join the array back into a string using thejoin()method. Here’s an example:
