Watching this video as a newbie Javascript developer was super insightful. A perfect crash course on possibilities of cool things you can do to modify strings in Javascript.

[@smyasir0]

Grand Summary charAt - returns character at specified index, myString.charAt(1) will return SECOND letter of string myString. charCodeAt - same as charAt but returns unicode instead. concat - concatenates string1 and string2, string1.concat(string2) // string1+string2 endsWith - condition check to determine if a given string ends with a certain character or string; string1.endsWith("abc") , fromCharCode - converts unicode values to characters, it is a static method of the String object, so you type String.fromCharCode(desiredCharCode) , where String is the string object and not any arbitrary string. includes - checks whether the string includes a specified character/string.. indexOf - tells the index of a specified string or character in the input string; inputString.indexOf("Dog"). In case of TWO or more occurrences of the same string/char in the inputString, it will tell index of only the first occurrence ! lastIndexOf - same as indexOf() but returns the index of the LAST occurrence of the specified char or string in the input string. match - searches the input string for matches of the REGULAR EXPRESSION specified and returns them in an array. repeat - repeats the string a specified number of times, inputString.repeat(3) // 3 times repeat inputString ! replace - searches a string for a specific sub-string or REGULAR EXPRESSION and replaces it with the specified string. inputString.replace("end", "END") search - searches the string for a specified sub-string or REGULAR EXPRESSION and tells it's position. slice - slices or extracts a specified portion of the inputString. inputString.slice(2,4), returns the stuff from index 2 till index 3 split - splits the string, into an array of sub-strings, upon the occurrence of the character specified. e.g inputString.split(" ") will split the string EVERYTIME a space (" ") occurs in the inputString and push the character coming UP TILL the space as a new entry in the array. ( but not including the space itself ? ) startsWith - checks if a string begins with a specified character/sub-string; conditional check. substr - similar to slice, extracts a sub-string from the inputString, starting from the given initialIndex, and going up to the number of subsequentDigits, including the character at initialIndex in the count as well. inputString.substr(initialIndex, subsequentDigits) . Watch in video if it's hard to understand. substring - Ditto copy of slice, better to look at stackoverflow.com/a/2243835 for a better understanding of differences. toLowerCase - makes ALL the letters in string to lower case toUpperCase - exact opposite of toLowerCase() . trim - removes WhiteSpace from EITHER SIDE of the inputString; inputString.trim().

Thank you

[@elilumilay9405]

Dude you saved me. I was doing a note and I keep replaying it to get the description. Thanks a lot!!

@@joonkim9302 did someone hurt your feelings boy?

[@carlosnani]

It was very very useful. Thanks a lot. I´d love 20 methods from another. :)

[@ronmoki1]

THANK YOU !!! FINALLY STRAIGHT TO THE POINT VIDEO !

[@AnnaMaria-or7se]

Excellent! Loved it.

[@frogboy831]

thanks so much!! i was having trouble differentiating all these.

love these vids. thanks!

[@more2learn279]

Awesome. Great summary. Helpful.

Thanks man this was so handy!

[@marimuthur9456]

Fabulous explanation thank you so much for sharing your knowledge to us keep posting like this....👌🏼👌🏼👌🏼👌🏼👌🏼😊🙏🏼

I like your last method of the list. So, Subscribed.

[@hattorihanzo5707]

very handy and useful. Thanks, FCC

[@paschalynukwuani6930]

You are awesome man. Guess what! You are also part of the reason people subscribe to this channel!

Thank you very much, that's very helpful!! Your voice sounds like Sheldon Cooper's', it was like watching 'Fun With Code" ! :D

Love it.. Please do: 20 number methods, 20 array methods.

Great video.

Thanks its very useful

Thank you!

[@MrTsamish]

Hi Sir, what is the difference between 'str.search' and 'str.indexOf'??

[@kirans936]

Just loved the tutorials 😍

[@Dipenparmar12]

Good one.....

[@oufcena5092]

var str = "freeCodeCamp is the best place to learn frontend and backend development"; str.includes("end"); //returns true str.startWith("free"); //returns true str.endwith("end"); //returns false str.match(/end/g); //returns an array str.repeat(3); //returns the same string concatenated to itself 3 times

Code editor and theme pls?

[@julioarruda8182]

I think Beau lives in a different speed

[@amberjones7573]

This video is the SH*T lol. I wish all videos were this quick and to the point. Plus gave me every option I needed. THANK YOU!

[@osamagamal495]

yeah short and straightforward but actually omitting some stuff like the difference between slice and substring and many other things.

[@Galejandro84]

*Excelent video*

[@KennyZzy]

how many string methods are there? Do you have to memorise it ?

[@juliankaww]

don´t need to memorise but is good to know that exists.

[@tinosebata520]

Hi I'm a new coder to java I was just wondering in an array I've seen coders use /g alot why is it used

[@JD-kf2ki]

Was looking for 'join'.

[@aphelioschenik3162]

Is the first one usless ? Cause we can just do like this stringOne [1] == stringOne.charAt(1)

[@randomdeveloper6456]

Another good short video for future references. :)

[@BrendanMetcalfe]

A lot of these are similar in Python as well

[@Altoids101]

How many string methods do you people need?

[@AB-vl4yb]

Difference between slice and substring stackoverflow.com/questions/2243824/what-is-the-difference-between-string-slice-and-string-substring

[@PavanKumar-os9xj]

Good

[@patrickmayer9218]

If only js strings weren't immutable! Regardless, thanks for the video!

[@satheeswaran9210]

Cool

[@BrendanMetcalfe]

👍👍👍

[@freddyperla7944]

I'm so used to char as in "CHARCOAL" not char as in "CARE"

[@akugoms7736]

whats the use of this all?

[@diegofreire7827]

For eg. I could use these methods in Bioinformatics stuff to manipulating DNA sequences of ACTGs

[@smyasir0]

any easier use ?

[@foxxxof]

@@smyasir0 Maybe creating user names from first and last names. Re-formatting documents with extra spaces, or finding incorrect capitalization - or changing an acronym to be all caps within a document . Finding specific characters within data. The concatenation feature could be used in many many ways.

[@gilsonviana4936]

In my opinion, for beginners is far more effective to learn - how to interact with object types - using LOOPS and CONDITIONALS then to learn a dozen of prototype methods. Not saying that you DON'T need to learn it though.

[@lalaithan]

This is a part of a playlist, including that topic.

[@peacefuldeityspath]

I can make a password cracker in js learning this LOL

[@peacefuldeityspath]

@Neutral Me • 13 years ago too late buddy

[@nested9301]

use your code for good

[@WebboTravels]

For those wondering why 1 is r it's because the computer starts counting at 0 so f=0

[@Challenge9000]

'Care.' ...ok

[@osvaldogalvez4776]

man i had to slow him down hahaha

[@jeffenriquez9929]

Anyone else pronounce 'char' as /CHär/??

[@juanmatapatpinoy]

Maybe u can change ur title in 20 JS string methods in 6:59, not 7mins 😅lol.

[@danielgarr4030]

i got lost at /end/g

[@javadkhalilarjmandi3906]

You are complicating the explanation when it is not necessary, you use big words which are just confusing and useless. You could do much better.
