JS easiest (short code) way to check if a string contains certain text (multiple texts)...

Question

check if the following string contains these texts:
validColors: “blue”, “green”, “yellow”, “white”

string “my shirt is blue”;
Now, how can we check if the string contains any of the valid colors easy.

Ok know there are different method, I’ll go ahead and tell u the ones I know:
I could use an if statement,
I could use a switch (){case...}

So, I’m wondering if there is an easier way to do it besides the methods I listed above.

Answer 1

Regex it bro.

Var mypattern = /blue|green|yellow|white/ ;

Var mystring= " type here your random string with or without color" ;
Var result = mypattern.test(mystring) ;
Console.log(result);

If console value true
Means contains valid color
If false it doesn't have valid color .
Hope it will work as you want.
Try it.

Answer 2

Another way, array methods:

const validColors = ["blue", "green", "yellow", "white"];
const str = "my shirt is blue";
const found = str.split(" ").some(r=> validColors.includes(r));
