I want to change all the text on the checkout page. I have refer many documents.

But I want to understand flow that it will work.

Has anyone idea about it?

I want to do customization on checkout page.

You can change text using i18 CSV translation method.

In your theme directory (For example)

magento2/app/design/frontend/OrangeCo/orange/i18n/en_US.csv

Add the following like.

 "Payment Method:", "Your text"
 "Review & Payments", "Your text"
 "Apply discount", "Your text"

Run the deploy command to get localization changes:

bin/magento setup:static-content:deploy

I hope it helps!

Those texts above using js translation which loaded to local storage "mage-translation-storage"

Your text could be found and translated by those lines, you could add it to theme i18n csv or create a separated translation package from /app/i18n

"Payment Method:","Payment Method:",module,Magento_Checkout
"Review & Payments","Review & Payments",module,Magento_Checkout
"Apply Discount Code","Apply Discount Code",module,Magento_SalesRule 

The main point of this which you think this should not work because your deployment script.

As mentioned here you have to separate the lines of deployment scrips

So instead of using:

 php bin/magento setup:static-content:deploy en_US de_DE it_IT fr_FR es_ES 

Use

php bin/magento setup:static-content:deploy en_US
php bin/magento setup:static-content:deploy de_DE
php bin/magento setup:static-content:deploy it_IT
php bin/magento setup:static-content:deploy fr_FR
php bin/magento setup:static-content:deploy es_ES

Here is my sample deployment script when I work with multiple languages project

php bin/magento setup:upgrade; 
php bin/magento setup:static-content:deploy en_US -t Vendor/FrontTheme -t Vendor/AdminTheme;
php bin/magento setup:static-content:deploy de_DE -t Vendor/FrontTheme;
php bin/magento setup:static-content:deploy it_IT -t Vendor/FrontTheme;
php bin/magento cache:flush;
