How statistics are calculated
We count how many offers each candidate received and for what salary. For example, if a Ionic developer with Git with a salary of $4,500 received 10 offers, then we would count him 10 times. If there were no offers, then he would not get into the statistics either.
The graph column is the total number of offers. This is not the number of vacancies, but an indicator of the level of demand. The more offers there are, the more companies try to hire such a specialist. 5k+ includes candidates with salaries >= $5,000 and < $5,500.
Median Salary Expectation – the weighted average of the market offer in the selected specialization, that is, the most frequent job offers for the selected specialization received by candidates. We do not count accepted or rejected offers.

Where is Git used?
Collaborating in Code Catacombs
- Dev teams use Git to juggle their coding wizardry in one magical place, dodging the dread of overwritten spells (code).
Time-Traveling in Tech
- Git's like a tech time machine, letting programmers scoot back to the 'what did I just break' past or peek into the 'future' branches.
Unraveling Code Quilts
- In the patchwork of software, Git lets devs add, adjust, or utterly upend patches of code without yanking the whole quilt apart.
Merging Wizardry
- Git zaps chaos by letting a coven of coders merge their spells without summoning a four-headed bug monster.
Git Alternatives
Mercurial (Hg)
Mercurial is a distributed version control system like Git. It's designed for efficient handling of very large distributed projects.
# Clone a repository
hg clone https://example.com/repo
# Commit changes
hg commit -m "Commit message"
- Intuitive interface and commands for new developers.
- Supports large binary files better than Git.
- Less popular, fewer online resources than Git.
- Built-in web interface.
- No shallow cloning, can lead to large clone sizes.
- Plugins extend functionality.
Subversion (SVN)
Apache Subversion, a centralized version control system, emphasizes simplicity and linear development, unlike Git's distributed approach.
# Checkout a working copy from a repository
svn checkout http://example.com/svn/repo/trunk
# Commit changes to the repository
svn commit -m "Commit message"
- Centralized model may fit certain workflows better.
- File locking functionality for binary assets.
- Can be less intuitive for branching and merging compared to Git.
- Atomic commits assure partial commits do not occur.
- Smaller community, and slower development.
- Access control built-in.
BitKeeper
BitKeeper is a distributed version control system that was historically significant for hosting Linux Kernel development before the creation of Git.
# Get a copy of a repository
bk clone BK://example.com/repo
# Commit changes
bk commit -m "Commit message"
- Robust and reliable due to years of development.
- Commercial product with proprietary features.
- Less widespread adoption means a smaller community.
- Advanced workflows accommodate seasoned developers.
- Open-source version has limitations compared to the commercial one.
- Designed for distributed development without loss of data.
Quick Facts about Git
Git's Lightning-Fast Birth by Linus
Imagine the year 2005: cargo pants were in, and Linus Torvalds, the kingpin behind Linux, was itching for a slick, distributed version control system to empower programmers. Bored of the options on the table, Linus brewed up Git faster than a college student cramming for finals—literally over a weekend! No kidding, Git went from zero to hero in software management in the blink of an eye.
The Evolution: From Clunky to Chunky
Back in the old days, Git was a bit of a command-line beast—newbies would rather stick their hands in a cookie jar full of tarantulas than try to merge conflicts. But, as years passed, it went through so many versions it's like watching a Pokémon evolve. Nowadays, we've got graphical interfaces smoother than a fresh jar of peanut butter, making us almost forget the screams of devs past.
Shaking Hands with Hubert the Octocat
Imagine a world where Git’s decentralized power-wielding was all alone, like a superhero without a sidekick. Enter GitHub in 2008: the bustling metropolis where code lives, parties, and gets forked. Git repos found their social network, complete with a mascot that's more adorable than a basket of kittens—Hubert the Octocat. It's the cherry on top of the developer sundae.

# Git code so simple, your cat could write it:
git init
git add .
git commit -m "Initial commit, meow!"

Top 10 Git Related Tech
Command Line Proficiency
Whip out that terminal, because we're going back to basics! Being a maestro of command-line interfaces (CLI) is like having a swiss army knife in your coding tool belt. Whether you're conjuring up Git spells or juggling files, the command line is your trusty steed in the wild west of software development. Memorize those commands; 'git commit' will be your new 'abracadabra'!
Version Control with Git
Git's the big cheese of version control, the guardian of your code's history. Juggling multiple versions of your code without git can quickly become a circus act gone wrong. With Git, you'll be time-traveling through your project's timeline smoother than a DeLorean. Learn it, live it, love it. Simply 'git init' and start your journey!
git init
git add .
git commit -m "Initial commit"
GitHub / GitLab / Bitbucket
Choose your fighter! These platforms are the social networks for your code. Push your repos into the cloud and let them socialize, interact, and get stars (not the Hollywood type, though). It's like online dating for devs where you're looking for the 'perfect pull' instead of the perfect match. Git 'remote add' and push away!
git remote add origin
git push -u origin master
Branching and Merging Strategies
Branching's not just for birds and trees; in Git, it's how you keep chaos at bay. And with great branching comes great merging. You don't want a merge conflict to ruin your day—so plan your branches like you're planning a heist. Get that 'git branch' and 'git merge' down pat or prepare for branch warfare!
git branch feature-x
git checkout feature-x
git merge master
Continuous Integration/Continuous Deployment (CI/CD)
CI/CD is the factory pipeline for your code. Set your tests, builds, and deployments on autopilot, and watch the magic happen. It's like having a team of elves taking care of the menial tasks while you focus on being the coding Santa. TravisCI, Jenkins, or GitLab CI—pick your potion and automate!
Git Hooks
Ever wanted a personal assistant that yells at you when you mess up? Git hooks are your guardians at the gate. These scripts fire off at key points in the Git workflow and make sure you're not tripping over your shoelaces. So don't skip the 'pre-commit' hook, or you might push bugs straight to production—yikes!
# pre-commit hook example
#!/bin/sh
files=$(git diff --cached --name-only --diff-filter=d | grep '\.js$')
if [[ $files ]]; then
./node_modules/.bin/eslint $files
fi
Interactive Rebase and Cherry Picking
If you've ever wanted to rewrite history without a time machine, interactive rebase is your friend. Tidy up your messy commits and present a saga that even your QA team would admire. Cherry picking, on the other hand, is like plucking the best fruits from the tree—all the commit goodness without the baggage. Just 'git rebase -i' and 'git cherry-pick' to keep history squeaky clean!
git rebase -i HEAD~3
git cherry-pick commitHash
Merge Tools like DiffMerge or KDiff3
Merge Tools are the referees in the match of the merges, making sure everyone plays nice. They're like relationship counselors for your code differences, smoothing out the bumps and preventing ugly breakups (also known as merge conflicts). Strap on your conflict-resolving helmet and dive into the battlefield with style!
Git Flow Workflows
Git Flow is the organized party planner for your repositories, giving every feature, release, or hotfix a home. It's like throwing your code into neatly-labelled boxes instead of one massive pile. Embrace the 'feature', 'release', and 'hotfix' branches or risk becoming a coding nomad with nowhere to commit.
git flow init
git flow feature start amazing-new-feature
git flow feature finish amazing-new-feature
Understanding of Semantic Versioning (SemVer)
SemVer is like the measuring tape for your software's growth—it helps you version your releases sensibly and predictably. Breaking changes? Minor tweaks? Patch fixes? SemVer communicates this with three little numbers (and the occasional dash and an alpha). Study this mantra: 'Major.Minor.Patch' and version like a pro!
