console.log()
This is the method we all use…
console.error()
This method is useful while testing code. It is used to log errors to the browser console. By default, the error message will be highlighted with red color.
console.warn()
This method is also used to test code. Usually, it helps in throwing warnings to the console. By default, the warning message will be highlighted with yellow color.
console.clear()
This method is used to clear the console.
console.time() and console.timeEnd()
Both these methods are used in conjunction with each other. Whenever we want to know the amount of time spent by a block or a function, we can make use of the time() and timeEnd() methods. Both these functions take a string as a parameter. Make sure you use the same string for both these functions to measure the time.
console.time('timer');
<code>
console.timeEnd('timer');
console.table()
This method generates a table inside a console, for better readability. A table will be automatically generated for an array or an object.
console.table({a: 1, b: 2, c: 3});
console.count()
This method is used to count the number that the function hit by this counting method. This can be used inside a loop to check how many times a particular value has been executed.
for(let i=0; i<3; i++){
console.count(i);
}
console.group() and console.groupEnd()
These methods group() and groupEnd() allows us to group contents in a separate block, which will be indented. Just like the time() and the timeEnd() they also accept a label, of the same value. You can expand and collapse the group.
